Part 21

The plum trees sent from the central station the spring of 1914 made a very poor growth that season, owing undoubtedly to the fact that the roots were dry when reaching here, but this last season all but one made a splendid growth, and one No. 10, to my surprise, produced five plums that for beauty and eating qualities would place this variety in the front rank with the best in the state. We shall watch these trees with great interest and will report on their actions as they develop.

The four trees of No. 1 plum, sent here the spring of 1915 from the central station, made a splendid growth, each tree developing fruit buds in abundance.

Of the seven varieties of raspberries sent here the spring of 1913, three made good this last season. No. 2 bore a tremendous crop of very large fruit, in quality the best; No. 4 bore heavily, an all around good berry and apparently a good shipper; No. 7 produced a good crop, not quite as large as No. 2, but continued in bearing for a long period. Further testing will be necessary for these berries, but so far they look good.

There is little to say about grapes, except the growth has been good, and the amount of fruit buds started immense, but the frost and unsuitable weather told the tale--we won't repeat it.

Of strawberries we will say this: If the central station did nothing in five years except to produce the strawberry known as Minnesota No. 3, they have still done well. It is hardy, a good shipper, it is delicious with cream and sugar, a good canner, in fact a great big Senator Dunlap with no green core, but ripens to the tip. It is also a good plant producer.

The strawberry known as No. 1017, planted last spring, did well. It is a wonderful plant producer, having a very heavy, dark green foliage, it seems to be a good bearer of large, dark red berries.

With the wood on the fruit trees thoroughly ripened, and fruit buds in good condition, we may look ahead to the future with courage, believing that all things come to him that waits in Minnesota, providing he hustles while he waits.

RED ROSE BEETLE IS EASILY KILLED.--Did you ever wait patiently in the spring for your favorite Japanese rose to bloom and find when the buds were ready to burst that it was scaly and spotted around punctures made by the red rose beetle? Then did you vow once more to destroy the beetles when you saw the roses begin to wither from punctures made by the beetle in the stem?

The destruction of the red rose beetle is simple, according to a circular recently issued by the Minnesota state entomologist, University Farm, St. Paul. The method is to cultivate the ground around the rose bush early this spring and cultivate it again in the late fall. This will destroy many of the beetles, for they live in the soil in the winter. Then a few of the pests can be hand-picked and destroyed.

If they are still too thick, they may be removed next fall for safety to next year's blooms. The beetle lays its eggs in the hip of the rose. These can be seen after the rose is in full bloom as a black spot, covered over with no noticeable depression. The growing pests leave the old blossom by the middle of September and go into the soil until next spring.

The bush should be examined in the latter part of August for any flower hips containing insect larvae and all found should be plucked and burned. A few hours' work will insure a beautifully blooming bush next year.

The 1915 apple crop at this station was a complete failure, owing to the freezes of late May and early June. This apple failure, so far as I have been able to ascertain, was prevalent over the entire county of Cottonwood, although we could hear of plenty of apples being grown only a short distance over the county line in all directions excepting to the west of us.

[Illustration: A windbreak at Dewain Cook's, mostly white willow.]

The season has been one of cool weather and much rainfall, so much so that although we had no killing frosts this fall until October 5th, yet no corn or melons ripened in this vicinity. We quit spraying our fruit trees when the freeze came last spring and destroyed the apple crop, and the result has been that there was much scab on the foliage of many varieties of our apple trees. The Antonovka and the Hibernal seem to be about the healthiest in this respect. As to the fire blight there has been absolutely none at this station the season just passed.

As for plums we got a few bushels in the final roundup, De Sotos, Wolfs and Wyants mostly. Of the Japanese hybrids, we got a few specimens of the B.A.Q. The Emerald bore freely, but the fruit mostly either was destroyed by the brown rot or cracked badly just as they were getting ripe. The Tokata, one of Hansen's hybrids, gave us specimens of very fine fruit.

Of the apricot hybrids only the Hanska made any pretense of trying to bear anything, but the curculio got away with about all of them.

When I made the midsummer report most of Hansen's sand cherry hybrids were promising a good crop, but with the exception of the Enopa and Kakeppa, from which we gathered a few quarts of fruits, we got nothing. The brown rot, assisted by the curculio, took them all. It sure looks as if we ever expect to make a general success with these sand cherry hybrids and with the Japanese hybrids, we will have to be better educated along the line of controlling this disease that is so very destructive to the fruit of some varieties of plums, especially of those varieties that have sand cherry or Japanese blood in them.

We have to report a grand success with everbearing strawberry No. 1017, sent to this station from our State Fruit-Breeding Farm last spring. The season all through was favorable for that class of fruit. We kept all blossoms picked off till about the first of August, when we let everything grow, and there is a great number of new plants. These new plants, with a few exceptions, did not bear, but the old plants, the ones set last spring, we gathered from them, from about September 15 till the first hard frost, October 5th, a liberal crop of surprisingly fine fruit. The Americus, also an everbearing variety, treated exactly as we did Minnesota 1017, bore a great number of plants and some fruit in the fall. The berries were not so large as the 1017 nor so many of them. While it is a perfect flowering variety, most of the late blossoms blighted, which seems to be a weakness of this variety.

On November 5th our strawberry beds were all given a mulching with loose oat straw for a winter protection.

The several varieties of grape vines originating at the Minnesota State Farm on trial here have all made a vigorous growth. We have them all pruned and laid on the ground, and we intend to give them no other winter protection. They are in a sheltered location. In spite of the various freezes early in the season we got samples of fruit from most of the varieties. Minnesota No. 8 seems to be the earliest to ripen its fruit. The wild grape flavor is noticeable in all these varieties.

The various varieties of plum trees sent here from the State Farm made vigorous growth the past season and are looking healthy with the exception of Minnesota No. 21. Of the five trees of this variety each one has a great many galls on the body of the tree. It is probably what is termed black knot, only the galls have not turned black yet. They are apparently of too recent growth for that. It is probable that we will plant other trees in their places next spring.

PAINTING OF SMALL TREE WOUNDS USELESS.--It has long been the custom for horticulturists to recommend, and fruit growers to use, dressings of various kinds on the wounds of trees when branches are removed in pruning. A few years ago the New York Experiment Station decided to conduct some experiments to determine whether such practice was really of any value or not.

From results of this work, which have recently been published in bulletin form, it is concluded that the use of white lead, white zinc, yellow ochre, coal tar, shellac and avenarious carbolineum as coverings for wounds under five inches in diameter is not only useless, but usually detrimental to the tree. This is particularly true of peaches, and perhaps of some other stone fruits, which, according to recommendations, should never be treated at all.

The substances mentioned often injure the cambium layer to such an extent that the healing of wounds is greatly retarded. Of the substances experimented with, white lead proved to be the best and is recommended wherever anything is used. But it is not thought worth while to use even white lead for wounds two or three inches or less in diameter, though it may be advisable to use it on wounds where very large branches have been removed.

On the larger wounds, where much surface is exposed to decay, the white lead will help to keep out moisture and the organisms which cause decay. The smaller wounds, however, heal so quickly that the evil effects of the covering may more than offset the benefits derived from its use.--R.A. McGinty, Colorado Agricultural College, Fort Collins, Colorado.

About twenty-six years ago a plantation of white spruce was made at this station. The trees flourished for several years and bade fair to become a permanent success, but some six or eight years ago they began to fail and many of them have since died. The survivors are all in poor condition. It seems that this tree is not well adapted to prairie conditions, at least not to the prairies of Southwestern Minnesota. Its native range is much further north. Here it evidently suffers from heat and dryness. The Black Hills spruce is commonly regarded as belonging to the same species. It has not been tested nearly so long, but so far it seems to be entirely hardy.

Something like thirty years ago a few trees of black spruce, a few trees of European larch and a few trees of balsam fir were planted here. They have long since disappeared. White pine planted at about the same time disappeared with them. A single tree of Scotch pine planted at about the same time, standing in the open, is gnarled and crooked and shows a great many dead branches. A forest plantation of several thousand Scotch pine, made something like twenty-two years ago, is still in good condition. Many of the trees are from twenty-five to thirty feet high. Some of the smaller trees have been over-topped and smothered out, but generally the trees seem healthy. A few hundred of the black, or Austrian, pine were set at the same time. They are about two-thirds of the height of the Scotch pine, but they are as healthy and vigorous trees as one would care to see. Some trees of rock, or bull, pine (Pinus scopulorum) were set at the same time. They have grown at about the same rate as the black pine and are healthy, vigorous trees.

Norway spruce has done better here than white spruce, some old trees fruiting freely. The Colorado blue spruce (Picea pungens) seems to be our best spruce, and so far as tested the Black Hills spruce is a good second. Douglas fir has been planted in a small way in the parks, but it is young yet.

It seems probable that the Scotch pines in the forestry plantation owe their comparatively good condition to the shelter they get from the hot winds from being planted close together, and from the fact that they are partly protected by the black pines planted to the west of them. The single tree of Scotch pine above referred to has had garden cultivation for thirty years, but it seems likely that it was injured by the same hot winds that killed the white pine and the larch. The Scotch pine is a native of Northern Europe, Norway, Sweden, Denmark, Scotland, Normandy (near the ocean) and Germany and Russia around the Baltic, and all these countries have a moist, cool climate. The black pine is a native of Southern Europe, growing all the way from Southern Spain to the Taurus Mountains in Asia Minor. In its native habitat it has become accustomed to the hot winds that often sweep across the Mediteranean, the burning sirocco of the Great Sahara. The dwarf mountain pine, Pinus Montana, grows in the Pyrenees, in the Alps, in the Carpathians and in the Balkan Mountains, so that it, too, often encounters the hot winds that come across from the African deserts. It is probable that the ability of the black pine, the dwarf mountain pine, the Black Hills spruce, and the rock pine to flourish on the prairies of Southwestern Minnesota is due to the fact that all these trees have become accustomed to resisting the hot, dry winds that often reach them in their native habitats.

The Norway spruce (Picea excelsa) in its many varieties is native to almost the whole of Europe, extending from north of the Arctic Circle to the Pyrenees and Balkan Mountains in Southern Europe. We could then expect that trees from the Pyrenees or from the Balkans might be so well accustomed to the hot winds from Africa as to make them resist, at least for some time, the hot winds of the prairies. And they do seem to stand better than the white spruce or the balsam fir or the white pine.

Some report should be made on the material sent out for trial from the State Fruit-Breeding Farm. The strawberry, No. 1017, made a fine growth, and promised a large crop of fruit in September, but a few days of quite dry weather, following a very wet spell, ruined the crop at ripening time.

The raspberry, No. 4, is a great producer of sprouts and multiplies enormously, but it seems to be a rather shy fruiter, and the fruit is not of the highest quality. It is intermediate in season. No. 5 is a much larger and better berry, although not quite so hardy. Both came through the winter, without covering, in good condition. No. 8 seems to resemble the old Columbian. It does not sucker much. It is a large, late berry of good quality. It was covered, so its hardiness is untested. Prof. Hansen's Oheta is a berry of much promise. It is of fine quality and fruits abundantly.

The hybrid plums were sprayed with a commercial dust spray but not effectively enough, for the fruit all rotted. We shall try more thorough spraying next season.

Patten's Greening, Oldenburg, Okabena and Simbrish No. 1 produced a good crop of apples. With us Okabena is undersized, of poor flavor and an extremely poor keeper.

The Growing of Vegetables for Canning.

M. H. HEGERLE, PRES. CANNING FACTORY, ST. BONIFACIUS.

The state authorities, through the Agricultural Farm and other sources, are doing good work promoting and encouraging the growing of vegetables, but it seems more could be done towards the marketing and conservation of these vegetables after they are grown.

The growing season for vegetables in this state is comparatively short, and although during that short period everybody eats vegetables, every grocer's show windows, and even the sidewalks, are used to display them, and a tremendous business is done, yet there are tons and tons of nice fresh vegetables go to waste, not only for the market or truck farmer but in every family garden--be the same ever so small, there is a steady waste going on, all of which could easily be conserved _by canning_.

Canning is simply putting the fresh vegetables in tin cans or glass jars (the latter are much more expensive, but no better), steaming and sealing them and setting aside until wanted. By doing this every truck farmer, and any one having ever so small a garden, could conserve enough which otherwise would go to waste to keep them in real fresh vegetables all winter.

Of course the thousands living in the cities having no garden can not do this and are therefore dependent on the canning factory for their fresh vegetables, and here is where my topic comes in, _the growing of vegetables for canning_.

It is no trick to grow vegetables for home canning, any variety will do. You need not select a big lot of one kind, and you need not sort for size or color. Just take the surplus as you find it in your garden from day to day. All it needs is, it must be fresh and it must be thoroughly clean--but growing for the canning factory is different. To line up fifty to 200 growers to sow the same seed, to plant, harvest and bring to the factory just when in right condition, requires time and hard work. This really is the hardest problem the canning factory has to solve, and that is the reason why all successful canners grow at least part of their product.

You must remember vegetables put in cans will come out just as you put them in. If you put in stale, tough, stringy beans you will be sure to find them there when you open the can, but if you put in fresh, tender beans, peas, corn or whatever else, you will find these exactly as you put them in, and it's immaterial whether you open this can the first, second or tenth year. We must not forget that vegetables properly sterilized and sealed will keep indefinitely, and they require no preservative of any kind. No canning factory uses any preservative, and no home cannery should use them.

[Illustration: Upland Farm, St. Bonifacius, Minn.]

There was a time when canning was considered an art or a secret. I remember receiving circulars offering for sale the secrets of canning, and while in the grocery business some twelve years ago I sold thousands of packages of canning compound. These canning compounds, after a thorough examination by our State Food Department, were found not only worthless but harmful if put in canned foods.

_Remember_, to can vegetables successfully, it requires no canning compound or preservative of any kind, simply fresh and thoroughly clean vegetables.

Fresh vegetables are a good, healthy food, we all know this; and besides they are cheaper than meat; therefore should be on our tables two or three times a day. But mind you, they must be fresh, and while for some of us during the growing season it is comparatively easy to get them fresh, yet during the rest of the year, say eight to ten months, real fresh vegetables in bulk are hard to find and high in price. A lot of so-called fresh vegetables shipped in from a distance at best require several days to make the rounds through the grower, the shipper, the jobber, the retailer--to our tables and are really not fresh. They have become stale, and by coming in contact with different kinds of material have lost their delicate flavor. Therefore to insure real fresh vegetables for our tables, at least during the winter months, we must take the canned article.

All of us remember how most everything in the grocery line was handled in bulk, dried fruits, cereals of all kinds, coffee, tea, etc., was displayed on the counters, along the aisles and even outside along the sidewalk, handled and examined by any one and exposed to dust and flies. Just about the same way are vegetables in bulk handled today. Where is the grocer who would go back to those days, and where is the public that would patronize him?

Mrs. Glenzke: What vegetables do you can?

Mr. Hegerle: We can corn; beans, string and wax; apples, tomatoes, etc.

Mrs. Glenzke: How do you manage to get the farmers to bring them in? In Wisconsin it was a failure. As you say, they came when they got their work done, and the whole bunch came there at one time.

Mr. Hegerle: That is the hardest work, to get the growers to bring the vegetables when they are in the right condition and when they should be canned.

Mrs. Glenzke: There are five canning factories in that neighborhood now, and there isn't a one of them that allows the farmers to bring their stuff. They rent the farmers' land for themselves. For miles and miles you can't find a farmer that hasn't rented his farm.

Mr. Hegerle: You have to have the vegetables at the right time.

Mrs. Glenzke: They use the farmer's team and give him all the assistance they can. It does away with having them all at one time. I have seen twenty-five farmers come at one time. I don't see how you manage it.

Mr. Hegerle: We have had a lot of trouble, and we are growing some of our vegetables.

Mrs. Glenzke: You can raise four successive crops of peas on the same ground, and you can make that work all right. They used to can squash, corn, tomatoes, and they have got down to peas entirely.

A Member: Doesn't most of that trouble arise from the low prices?

Mr. Hegerle: No, not entirely. The price when contracted is satisfactory, and we find in our experience in growing our own vegetables we can grow them cheaper than what we pay to the growers. But we wouldn't grow any if we could get the growers to bring them in when they are in the right shape. When corn is at a certain stage to make a good canned article it has got to be brought in that day, and if the farmer don't bring it, if he has a state fair on or a wedding or a funeral or something and delays it a day or two, then it is all off; that corn is lost.

Mr. Sauter: I would like to know which is the best beans for canning, the yellow or the green?

Mr. Hegerle: Well, we prefer the Refugee, both in wax and green. We prefer them because they are the best in flavor we have.

Mr. Sauter: Which is the best, the flat or the round of the wax?

Mr. Hegerle: Round is preferred by the trade, by the grocers or jobbers. I have kept the flat wax beans for my own use of those that we can.

Mr. Sauter: Don't the flat ones bring a little more than the round ones?

Mr. Hegerle: Well, probably the first or second picking, but you can't pick them as often as the other variety. The Refugee you can pick four or five or six times, and the flat beans can only be picked two times.

Mr. Anderson: I would like to ask what you pay for beans for canning purposes?
