n the boards, and of the same length as the original
lintels. The broken-out walls are to be trimmed to afford solid resting
places for the new lintels, which are to occupy the same horizontal
planes that the old ones did. The openings above the lintels are to be
filled in in the same manner as the underpinning previously described,
the tinder wall surfaces being carefully dressed to afford solid
horizontal bearings, the brick work being set back 1 inch from the wall
surfaces and plastered with a coating of cement mortar to bring it out
flush with the wall.

4. BRACING

One wooden brace and two iron braces are to be put in, as shown upon the
plan hereto annexed. The wooden brace is to be of one piece, or of two
pieces well bolted together, of selected lumber, free from knots and
other imperfections, squared, and measuring 6 by 8 inches in cross
section. The iron braces are to be of 1 inch diameter, best quality
wrought-iron rods. The bearing plates, four to each rod, are to be not
less than 10 inches in diameter, of sufficient strength, and securely
and permanently fastened to the braces.

5. WIRE FENCING

Such area as may be determined is to be fenced with the best quality of
galvanized iron barbed wire, strung upon posts placed 20 feet apart. The
posts are to be of mesquite, not less than 3 inches in diameter and of a
reasonable degree of straightness (not varying more than 5 inches from a
straight line). The posts are to be at least 6 feet 6 inches long and
are to be planted perpendicularly with 4 feet 6 inches clear and at
least 2 feet below the ground surface. Three lines of double wire are to
be stretched upon and securely fastened to the posts, the first at a
distance of 2 feet from the ground, the second at 3 feet, and the third
at 4 feet from the ground. Two gateways are to be provided, at such
points as may be directed, the side posts to be of squared timber, 6 by
6 inches in cross section, and the gates to be made of sawed lumber 1
inch by 5 inches, hung upon good iron hinges, and leaving a clear space
of not less than 12 feet when open, the whole to be executed in the best
and most workmanlike manner.

6. ROOF

The building is to be crowned by a roof of corrugated iron, supported in
the manner shown in the accompanying plan and sections. The uprights are
to be of selected squared lumber 1 foot square, each in a single piece,
the lower ends planted at least 3 feet below the original ground level,
and
