Dr. Huestis: Well, I dig up the ground a little in the spring. The roots are very near the surface, not very penetrating, and I cultivate around the roots, but I am careful not to cut them. Every fall I put a good mulch of leaves and hay around them. I have been a little fearful they would winter-kill. I wouldn't lose one of them for ten dollars, and I think it well to mulch them, leaving a little space at the base.

Mr. Andrews: Are the roots exposed in some cases?

Dr. Huestis: Yes, I noticed on two of the older trees, those that have been in eight years and have borne six crops, you can see the roots on one side, the top is exposed a little, and I think it would be well to put a little dirt on those another year. The stock of these dwarf trees is slow growing with a rapid growing top, and that is what dwarfs them. I have transplanted one tree three times, which would make four plantings in eight years, and that tree bore almost as much fruit last year as any of them. In another case once transplanted I think the tree is better than the others that were left.

[Illustration: Dwarf Yellow Transparent, bearing 96 apples, third year from planting at Dr. Huestis'.]

As I said before, if I was planting an orchard I would put dwarf trees between, and by the time they had borne three or four crops, and you were expecting a crop of fruit from the standard trees--about seven years from the time you put them in--I would put the dwarf trees as fillers, costing about forty cents apiece, and by the time they are bearing nicely your friends would have seen those, and I believe would want them at the time you want to take them out. I believe I could sell any of mine for three or four dollars apiece. I think that would be one way of disposing of them after you wanted to take them out of the standard orchard on account of room. That is just a thought of mine.

When I got my first ones eight years ago I gave one to a man who lives in North Minneapolis, at 1824 Bryant Avenue North. Any one can see it who lives up in that section. The first year he had twenty-nine apples, and it has borne each year since. The one which I have transplanted and which bore last year is a Bismarck. It is a little better apple, in my mind, than the Duchess. It is a good deal like the Duchess but is a better keeper and has a better flavor than the Duchess.

[Illustration: Dwarf Bismarck, fourth year, at Dr. Huestis']

I would like to read a quotation to show that the dwarf tree is not a late thing. Recommending dwarf trees for gardens, "Corbett's English Garden," published in 1829, says: "I do hope if any gentleman makes a garden he will never suffer it to be disfigured by the folly of a standard tree, which the more vigorous its growth the more mischievous its growth to the garden."

Marshall says, "The fewer standard trees in the garden the better." Also that the dwarfs are less trouble to keep in order and are generally more productive, and that "placed eight or nine feet distant, pruned and kept in easy manner, they make a fine appearance and produce good fruit." W.C. Drury, highly regarded as a modern English authority, writing in 1900 says: "For the private garden or for market purposes the dwarf, or bush, apple tree is one of the best and most profitable forms that can be planted." He also says: "The bush is one of the best forms of all, as it is of a pleasing shape and as a rule bears good and regular crops."

Mr. Clausen: Don't you have trouble with the mice?

Dr. Huestis: No, sir, have never seen any.

Mr. Clausen: I had an experience a few years ago. My neighbor made a mistake; he was hauling straw around his apple trees, and he happened to take one row of mine. We had no fence between us--and he laid the straw around the trees. I found when I came to examine these trees in the spring they were all girdled around the bottom. I am afraid to mulch.

Dr. Huestis: I never have taken any chances. Ever troubled with the mice at your place, Mr. Weld?

Mr. Weld: A little.

Dr. Huestis: I have never had any trouble with the mice. I always put on a lot of old screen that I take from the cottages that is worn out and put a wire around it so the mice can't get through it. We must protect from mice and rabbits.

Mr. Kellogg: How soon do your dwarf trees pay for themselves?

Dr. Huestis: I don't know. I reckon these four have paid about twelve per cent. on fifteen or twenty dollars this year, and they have right along. They have paid me better so far during the eight years than the standards. That might not apply in eight more years, but for a city lot, a man who has fifty square feet, how many apple trees could he put in that seventeen feet apart? Nine standard trees. In that same plot of fifty feet square he could put in sixty-four dwarfs, and it would be a nice little orchard. I think it is more adapted to the city man. The ordinary farmer would neglect them, and I should hate to see a farmer get them, but I would like to do anything for the man living in the city with only a small plat of land--my vocation being in the city, my avocation being in the country.

Mr. Kellogg: Are those honest representations of the different apples from the dwarf and the standard?

Dr. Heustis: I don't know. Those are a fair sample of those I found in a box on exhibit and are Red McIntosh. They are better colored than mine, most of them are like this (indicating). I find the Yellow Transparent that I have budded on the standard better on the dwarf than on the standard.

Mr. Kellogg: Does it blight any?

Dr. Huestis: No blight; there hasn't ever been a blight. I think that is one reason why I feel I could recommend them quite conscientiously. Other trees have blighted when the conditions were favorable.

TWENTY-FIVE BY SEVENTY FOOT PLOT WILL PRODUCE ENOUGH VEGETABLES FOR A SMALL FAMILY.--Even the smallest back yard may be made to yield a supply of fresh vegetables for the family table at but slight expense if two or three crops are successively grown to keep the area occupied all the time, according to the garden specialists of the department. People who would discharge a clerk if he did not work the year round will often cultivate a garden at no little trouble and expense and then allow the soil to lie idle from the time the first crop matures until the end of the season. Where a two or three crop system is used in connection with vegetables adapted to small areas, a space no larger than twenty-five by seventy feet will produce enough fresh vegetables for a small family. Corn, melons, cucumbers, and potatoes and other crops which require a large area should not be grown in a garden of this size. Half an acre properly cultivated with a careful crop rotation may easily produce $100 worth of various garden crops in a year.

Plums That We Already Have and Plums That Are on the Way.

_The Brown Rot (Monilia) a Controlling Factor._

DEWAIN COOK, FRUIT GROWER, JEFFERS.

By the term "plums we already have" for the purpose of this paper we shall include only those varieties that have given general satisfaction over a large territory and for long term of years, and in the writer's opinion every one of such varieties are of full blooded, pure Americana origin.

The DeSoto takes the lead of them all. It undoubtedly has more good points to its credit than any other plum we have ever grown. The Wyant and the freestone Wolf are considered as being the next two most popular varieties. These were all wild varieties, found growing in the woods of Wisconsin and Iowa many years ago.

There are a few other Americana varieties that are nearly as good as are some of those enumerated, but at present we shall not attempt to name them. There are many otherwise fine varieties that are not included in this list of plums we already have, but because of a certain weakness of the blossom they require to be intermingled with other varieties, or the blossoms do not fertilize properly. They only bear well when conditions are very favorable. We class such varieties as being not productive enough.

Many attempts, with more or less--generally less--success have been made to improve our native plums through the growing of seedlings. Mr. H.A. Terry, of Crescent, Iowa, has done more of such work in his day than any other one man. His method was to plant the Americana kinds, like the DeSoto, alongside of varieties of the Hortulana type, like the Miner, then growing seedlings from the best plums thus grown. From such cross bred seedlings Mr. Terry originated and introduced a great many very fine varieties. But where are they today? The Hawkeye and the Terry are about the only ones the general public knows very much about. I will venture this statement, that as far as I know there is no variety of native plum in which there is an intermingling of Hortulana or Chickasaw type that has proven productive enough to be generally profitable.

The Surprise plum belongs to this type, as also does the Terry plum. The Terry plum we want to keep a while longer, not because it is a mortgage lifter for the growers but because of the extraordinarily large size of its fruit, as well as for its fine quality.

There are many injurious insects and fungous diseases that tend to make life a burden to the man who tries to grow plums in a commercial way. Among the insects are the plum curculio and the plum tree borer, better known as the peach tree borer. The curculio sometimes destroys all of the fruit on the tree, and the borer very often will destroy the whole tree of any variety.

Among the fungous diseases are the shot hole fungus and the plum pocket fungus, but the worst of all is that terribly destructive disease of the plum known as the brown rot. This brown rot fungus sometimes destroys the whole crop of certain varieties, besides injuring the trees sometimes as well. This one disease has done more to make plum growing unpopular than all other causes combined. Give us a cheap and efficient remedy, one that will destroy the rot fungus and not do injury to the foliage, buds or tree, and a long stride will have been made towards making plum growing popular as well as profitable.

_Japanese hybrid plums._--Just now the Japanese hybrid varieties are attracting considerable attention. One prominent Minnetonka fruit grower said this to me about them:

"Mr. Cook, what is the use of making all of this fuss about these new plums? Plums are only used for the purposes of making jelly anyway, and we can usually get a dollar a bushel for our plums, and they would not pay any more than that, no matter how large and fine they are."

This brought me up with a jerk, and I have concluded that no matter how advanced a place in horticulture these new hybrid plums may eventually take, that there will always be a place for our native varieties, even if only for the purpose of making jelly.

It seems to the writer that in view of the fact that after many years' attempt to improve our native plum through the process of seed selection--and we have made no material advancement in that line--that the varieties of plums that are on the way must almost of necessity be the product of the Americana and some of the foreign varieties of plums.

Mr. Theo. Williams, of Nebraska, a few years ago originated a great many varieties of these hybrid plums. He claimed to have upward of 5,000 of them growing at one time. Only a few of them, however, were ever sent out. Of these the writer has been growing for quite a number of years the Eureka, Emerald, Stella, Omaha, B.A.Q. and some others. As a class they are all reasonably hardy for my section. They grow rapidly, bear early, usually the season after they are planted or the top grafts set. They set fruit more freely and with greater regularity, as the seasons come, than do the best of our native varieties. The fruit is of larger size and of firmer flesh, while the quality of some of them, like the B.A.Q., ranks rather low. The quality of others of them, like the Emerald, is almost beyond comparison.

One year ago in answer to a question by the writer as to why the people of Iowa did not take more interest in the planting of these hybrid plums of Mr. Williams, Mr. C.G. Patten stated that it was because the plums rotted so badly on the trees. Now, Mr. Patten stated the situation exactly--most of these fine varieties are notoriously bad rotters. The brown rot seems to be a disease of moist climate. Nature's remedy is an abundance of sunshine and a dry atmosphere, but we cannot regulate the climate. Prof. Hansen has sent out a few varieties of these Japanese Americana hybrid plums, and our Supt. Haralson is doing a great work along this line. We can only hope--but cannot expect--that Mr. Hansen's hybrids or Mr. Haralson's hybrids as a class will prove more resistant to the brown rot than do those of Mr. Williams of the same class.

We have hopes that from some of Mr. C.G. Patten's hybrids of the Americana and Domestica plum will come some varieties worthy of general planting, and also of Prof. Hansen's crosses of the Americana plum and the Chinese apricots.

There is another class of hybrid plums that are something wonderful in their way, beginning to bear nearly as soon as they are planted, the very earliest of all plums to ripen its fruit, immensely productive and of finest quality. I refer to Prof. Hansen's sand cherry hybrid plums. My opinion is that Prof. Hansen has done all that man can do in the way of producing elegant varieties of this class of fruit. But there is the uncertainty, however, or perhaps I had better say the certainty, that the brown rot will take a good portion of the crop nearly every season--sometimes only a part of the crop, and other seasons it may take the entire crop of these fine sand cherry hybrid plums.

Bordeaux mixture has been the one remedy advertised for years for the control of this disease, and however well it may work in the hands of experts of the various university farms, it has not proved uniformly successful in the hands of the ordinary fruit grower.

Now, if some medicine should be invented, or some magic made, whereby the brown rot would be banished from our orchards then a great many of the fine varieties of hybrid plums would be transferred from the "plums that are on the way" to the list of "plums that we already have." The brown rot is a controlling factor.

Mr. Kellogg: What do you know about the Surprise?

Mr. Cook: Oh, I know a little more than I want to know about it. I have had the Surprise a good many years.

Mr. Kellogg: You have been surprised with it?

Mr. Cook: Yes, sir, I have been surprised quite a bit, but in the last two years since the plum crop failed there have been a few plums on the Surprise trees, but for a great many years when other plums bore heavily we got nothing.

Mr. Hansen: Do you know of any plum that has never had brown rot?

Mr. Cook: In my paper--as they only allowed me fifteen minutes I had to cut it short, and I didn't say very much about the brown rot. All the Americana plums, and all varieties of plums I have ever grown, have in some way been susceptible to the brown rot, but some have been more resistant than others. Now, that is one reason, I believe, why the DeSoto takes the lead. It is less subject to the brown rot. We have here a moist climate, and sunshine and dry atmosphere is the remedy, but some of these varieties have such a peculiar skin it is resistant to brown rot, and it seems certain, I don't know, if it is not on account of the thick skin. The Wolf has a thick skin and is subject to brown rot, but the DeSoto is not subject to that so much but more subject to the curculio. The Japanese hybrid plums, Mr. Williams said at one time--I saw in one of the reports--that he had Japanese plums enough to grow fifty bushels of plums, but he generally only got a grape basket full. He didn't think very much of them. In these sand cherry hybrids, I think Mr. Hansen has done all that man could do.

Mr. Ludlow: What is the difference between the brown rot and the plum pocket fungus?

Mr. Cook: Professor Stakman will tell you that in a later paper, but it is an entirely different disease. The brown rot will work the season through. It will commence on some varieties and work on the small plums and work on the plums half-grown and on the full-grown. The plum pocket fungus, it works on the plums in the spring of the year and sometimes takes the whole crop. The Terry plum, I think, a year ago, it took the whole crop.

Mr. Kellogg: What is the best spray you know of, how often do you apply it and when?

Mr. Cook: Which is that for, for the brown rot?

Mr. Kellogg: Yes, for the plum generally.

Mr. Cook: Oh, I don't know of any. Let me tell you something, the plum as a class is very susceptible to injury from sprays. I know when Professor Luger was entomologist there was some talk of spraying plums for curculio, and some tried it, and while it generally got the curculio it killed the trees, and Professor Luger said that the foliage of the plum was the more susceptible to injury from arsenical poisoning than that of any other fruit in Minnesota. The Japanese hybrid plums, I think, will take injury a little bit quicker than the native, and when you come to the sand cherry plums it is extremely dangerous to spray with anything stronger than rain water.

Prof. Hansen: I want to talk about the lime-sulphur. We will probably have that in the next paper, only I want to say that seems to have taken the place of the Bordeaux mixture. Brown rot, that is something that affects the peach men too. In the state of Ohio in one year the peach men lost a quarter of a million dollars from the brown rot, the same rot that takes our plums. We are not the only ones that suffer from the brown rot. Well, they kept on raising peaches because they learned to control it, and if you are not going to spray I think you better give up. As to trying to get something that won't take the rot, it is something like getting a dog that won't take the fleas. (Laughter.)

Mr. Older: I had considerable experience in putting out seedling plums. When large enough to get to bearing there wasn't a good one in the whole lot. I got some plums, the finest I could pick out, and three years ago they first came into bearing, and one of my neighbors went over there when they were ripe and said they were the best plums he had seen, but since then I have had none. I got some Emerald plums from Mr. Cook. They were nice plums, and when he came to see them he said, "I came to see plums, I didn't come to see apples," but the brown rot gets a good many of them. I had some last year, and just before they ripened the brown rot struck them, and it not only took all the fruit but got the small branches as well. I don't know what to do about the brown rot.

Mr. Drum: I would say that my experience was something like Mr. Older's with the sand cherry crosses. They grew until they were large and I sprayed them with lime-sulphur. I couldn't see any injury from that until they were grown, nearly ripe, and then in spite of me in a single day they would turn and would mummy on the trees. I had a Hanska and Opata and the other crosses, and they bore well. They were right close to them, and the brown rot didn't affect them particularly.

Mr. Ludlow: I would like to ask these experts what is the life of a plum tree. Now, an apple tree, we have them that have been bearing for forty years, but my plum trees that were put out less than twenty years ago, they got to be a thicket and they don't bear any large plums at all. I introduced years ago, if you remember, the Ocheeda plum, that come from seedlings that we found in the wild plum at Ocheeda Lake. It is a very fine plum. I had about twelve bushels this year, and I have never seen a bit of brown rot in that variety of plums, although the other varieties, if they bore at all, they were brown rotted all over. The Ocheeda plum has a very thin skin, and when the rain comes at the right time and the sun comes out they all split open. That is its fault. But my orchard is getting old; it is twenty years old. I had a young man work for me, and he left me and bought a new place. I told him he could take up all the sprouts he wanted of those Ocheeda plums. He did so and put out an orchard of them. I think that was about ten years ago. This year while my plums didn't average me, my Ocheedas didn't average, over an inch or an inch and an eighth in diameter from that old orchard--he had sold out and gone to California--but from that orchard a man that never thinks of cultivating sold three wagon loads of the finest plums I ever saw.

Mr. Kellogg: How large were the wagons? (Laughter.)

Mr. Ludlow: Well, the ordinary wagon box. He hauled them and sold them in town. That was from an orchard that had been left without any cultivation.
