The estimates given on plate and cathedral glass are about as unsatisfactory as anything can be. They merely give the owner a general idea as to what to expect.

Electric-work prices are approximately correct for localities where the facilities for doing this kind of work are at hand. Door and table bell outfits are now sold and arranged ready to be set up. The methods of their adjustment are so simple that any one who can read can put them in.

The general statement may be made that these prices are approximately correct in all the larger markets; and that in cases where the building is far removed therefrom, there must necessarily be additions for travel of workmen, and other incidental expenses in the transportation of material and labor.

The following is the list of prices of material and labor upon which the building estimates are based:—

Excavating, $0.25 a yard.

Brick in the wall, $9 per M.

Mason work, $5.50 a yard, laid up.

Cement floors, $0.70 a square yard.

Timber, joist, and scantling, less than eighteen feet long, $17 per M.

No. 1 common boards, $18 per M.

Select common pine flooring, count measure, $26 per M.

Common flooring, count measure, $22.50 per M.

First quality yellow pine flooring, face measure, $37.50 per M.

Standard yellow pine flooring, face measure, $30 per M.

No. 1 poplar flooring, face measure, $28.50 per M.

No. 2 poplar flooring, face measure, $23.50 per M.

No. 1 stock boards, $20 per M.

No. 1 poplar siding or weather-boarding, $18 per M.

No. 2, $16 per M.

No. 1 pine siding, $22 per M.

No. 2, $20 per M.

Shingles, 16 inches clear butts, best, per M, $3.75.

Shingles, 16 inches extra, 10 inches clear butts, $3.25.

Pine lath, per M, $2.50.

Poplar and pine finishing lumber, $3.75 to $6 per 100 feet.

Oak or maple flooring, first class, $4 to $6 per 100 feet.

Oak finishing lumber, $4 to $6 per 100 feet.

Under certain conditions the above prices are subject to discounts.

Plastering: three-coat work, plaster-of-Paris finish, $0.25 a yard; two-coat work, plaster-of-Paris finish, $0.20; gray floated sand finish, three cents extra on above prices.

Painting, $0.06 per yard a coat.

Labor: common labor, $0.15 an hour; bricklayers and masons, $0.35 to $0.45 an hour; carpenters, $0.20 to $0.30 an hour; tinners, $0.30 an hour; painters, $0.20 to $0.30 an hour; plumber and helper, $0.50 an hour.

The above labor prices are those paid by the contractors. Rarely, however, are the maximum prices reached.

There are few subjects on which ideas vary so greatly as values. This fact may be made apparent when we call to mind that bids on a house let for $3,000 frequently range $1,000 higher than this figure.
