est care that the centres are set to exact position and level, and that the bearings for the metal-work on the masonry are perfect.

Eleventh. Whenever there are any adjustable rods used in a structure, see that they are properly tightened before the work is left, taking care that they are not screwed up more tightly than is really necessary.

(B) RAILS.

First. Examine all rails as soon as received, so as to see that there are no poor ones which have escaped the rail-inspector's eye, or which have been loaded for shipment after being rejected. Inspect also all other track-metal, such as angle-bars, bolts, and braces, so as to see that they are of the correct type and are delivered in good shape.

Second. See that all rails are laid to exact line and level, and that they bear properly everywhere.

Third. In draw-spans, make sure that the track-rails at the ends will not interfere with the operation of the draw.

(C) PAINTING.

First. See that, after proper cleansing and retouching with paint, the metal-work receives its first field-coat of paint as soon as practicable after erection, and that the next coat is applied as soon as practicable after the first field-coat is thoroughly dried, but in no case before.

Second. Make sure that all paints used are of the proper color, quality, and consistency, and that no adulterants or thinners are used; also, that all paint is properly applied.

Third. Look carefully to the painting of all close spaces between metal, and see that it is done effectively with a piece of cloth, according to the specifications.

Fourth. See that all portions of the metal-work, which are to rest on the masonry or which are to be embedded in the concrete, receive their two field-coats of paint in due time, so as to dry thoroughly before the said metal-work is erected.
