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.

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

[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

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.
