ss than 1" thick are sold by the square
foot, face measure. Dressed lumber comes in sizes 1/8" less than sawn
lumber. Regular sizes are:

5/8" dressed to 1/2"

3/4" dressed to 5/8"

1" dressed to 7/8"

1-1/4" dressed to 1-1/8"

1-1/2" dressed to 1-3/8"

2" dressed to 1-7/8"

Any of these may be dressed down to thinner boards, or resawn on a
special band-saw.

In ordering it is common to give the dimensions wanted, in the order
of thickness, width, and length, because that is the order in which
dimensions are gotten out. E. g.:

6 pcs. quar. oak, 7/8" x 6" x 3'0"
2 pcs. quar. oak, 3/4" x 7-1/2" x 15"

If a piece wanted is short the way the grain goes, the order would
be the same, thus: 3/4" x 11" (wide) x 6" (long). That is, "long"
means the way the grain runs. It is always safe to specify in such a
case. It is common when small pieces are ordered to add one-quarter
to the cost for waste.

In large lots lumber is ordered thus: 800' (B. M.) whitewood, dressed
2 sides to 7/8", 10" and up. This means that the width of any piece
must not be less than 10". Prices are usually given per "M," i. e.,
per 1000 ft.: e. g.: basswood may be quoted at $40.00 per M.

When thin boards are desired it is often economical to buy inch stuff
and have it resawn.

Some lumber is also ordered by the "running" or lineal foot,
especially moldings, etc., or by the piece, if there is a standard
size as in fence-posts, studs, etc. Laths and shingles are ordered
by the bundle to cover a certain area. 1000 4" shingles (=4 bundles)
cover 110 sq. ft. with 4" weather exposure. 100 laths (1 bundle) each
1/4" x 1-1/2" x 4'0" cover about 150 sq. ft.

There are several methods of measuring lumber. The general rule is to
multiply the length in feet by the width and thickness in inches and
divide by 12, thus: 1" x 6" x 15' / 12 = 7-1/2 feet. The use of the
Essex board-measure and the Lumberman's board-measure are described in
Chapter 4, pp. 109 and 111.
