, but this table represents ideal conditions, where there are no delays, mistakes, legitimate office expenses, nor foreman's time included.

_Summary_

The amount of material, as previously estimated, is 18,578 ft. B. M., which, at $40.67 per M, will make the total cost of framing $755.57.

SHEATHING _Quantities_ FEET B. M. Main roof, 2,200 sq. ft. × 1 in 2,200 Tower roof, 370 sq. ft. × 1 in 370 Porch roof, 637 sq. ft. × 1 in 637 Outside walls, laid diagonally, 2,417 sq. ft. + 10 per cent. 2,659 ----- Total sheathing 5,866

SHINGLES _Quantities_ Area to be covered (see wall sheathing), 2,417 sq. ft.= 24.2 squares Shingles, 4 in. wide, and 5 in. exposure, number per square 720 Number of shingles required, 24.2 × 720 17,424 Add 5 per cent. for waste 871 ------ Total shingles 18,295

_Cost_

The cost of sheathing in place is assumed to be the same as that for hemlock lumber, $40.67 per M. The total sheathing is 5,866 square feet, which, at $40.67 per M, will make the cost of sheathing $238.57.

The cost of shingles is based on the following analysis of the cost of 1,000 shingles in place:

1,000 shingles XXXX $ 5.50 [14] Labor: one man can lay about 700 shingles per day; wages being $3.20, 1,000 will cost 4.57 Nails (about) .25 ----- Cost per thousand $10.32

[14] Usually a man can lay more than 700 shingles per day, but the roof under consideration is very much cut up.

From the preceding estimate, the number of shingles required is 18,295, which, at $10.32 per 1,000, will make the cost of shingles in place $188.80.

_Summary_ Sheathing $238.57 Shingles 188.80 ------- Total cost of sheathing and shingles $427.37

FLOORING _Quantities_ SQUARE FEET First floor, area (net) 1,312 Second floor, area (net) 1,312 Attic floor, area (net) 1,071 Porch floors, area (net) 523

HEMLOCK UNDERFLOORING

Unmatched underflooring is used under the first and second floor. Its quantity is 1,312 × 2 = 2,624 feet B. M.

RIFT-SAWED YELLOW-PINE FINISH FLOORING

The total area of the first, second, and third floors is 3,695 square feet. Adding 25 per cent. for waste, the quantity of ⅞-inch flooring is 3,695 square feet + (3,695 × .25) = 4,619 feet B. M.

YELLOW-PINE PORCH FLOORING

Increasing the net area of the porch floor by 25 per cent., the flooring required is 523 square feet + (523 × .25) = 654 feet B. M.

_Cost_

The estimated cost of flooring may be analyzed as follows:

_Cost of 1,000 Feet B. M., Rough Flooring_ [15] 1,000 ft. B. M., hemlock $27.00 Labor 10.00 Nails, 33 lb., at $2 per 100 pounds .67 ----- Cost per thousand feet B. M. $37.67

_Cost of 1,000 Feet B. M., Finish Flooring_ 1,000 ft. B. M., rift-sawed yellow pine $55.00 Labor, including striking joints 16.00 Nails .67 ----- Cost per thousand feet B. M. $71.67

_Cost of 1,000 Feet B. M., Porch Flooring_ 1,000 ft. B. M., No. 1 yellow pine $45.00 Labor 16.00 White lead for joints (about) .50 Nails .67 ------ Cost per thousand feet B. M. $62.17

[15] The cost of this hemlock is $1 cheaper per thousand than that used in the framing, since shorter lengths may be employed.

_Summary_ Hemlock, 2,624 ft. B. M., at $37.67 per M $98.85 Rift-sawed yellow pine, 4,619 ft. B. M., at $71.67 per M 331.04 Yellow pine, 654 ft. B. M., at $62.17 per M 40.66 ------ Total cost of flooring $470.55

PORCH CEILING, YELLOW PINE _Quantities_ FEET B. M. Porch ceiling, same as porch flooring 654

_Cost_

The cost of yellow-pine ceiling is $45 per thousand feet B. M. Since there is no white lead to be used and the joints are not struck, $11 will pay for laying it. The nails will cost 67 cents, which will bring the cost per thousand feet B. M., up to $56.67. Therefore, 654 feet B. M., yellow-pine ceiling, at $56.67 per thousand, will cost $37.06.

CORNICE, SPANDRELS, ETC., WHITE-PINE DRESSED LUMBER _Cost_ Cornice, 393 lin. ft., at 50 cents per foot $196.50 Spandrels, 357 lin. ft., at 12 cents per foot 42.84 Base, 128 lin. ft., at 6 cents per foot 7.68 16 porch posts, 8" × 8" × 9' at $4 each 64.00 ------- Total $311.02

_Summary_ Yellow-pine ceiling $ 37.06 White-pine dressed lumber 311.02 ------- Total $348.08

_Recapitulation of Cost of Carpentry_ Framing $755.57 Sheathing and shingles 427.37 Flooring 470.55 Porch ceiling, cornice, etc. 348.08 --------- Total cost of carpentry $2,001.57
