"The deck-house, including the roof of the same, is to be framed with good and sufficient angles and tees, prepared to receive the fireproof blocks and the skylights.

"Light Cast-Iron Wor.

All cast-iron work is to be particularly well made and finished and of uniform thickness; and all castings must be clean and sharp." This specification is perhaps as clear as it is possible to make a specification for cast iron. Nevertheless, there is room for trouble to arise from difference in opinion as to what the terms "particularly well made and fin ished" and "clean and sharp" may mean.

"The front column at the rear entrance, first story, is to be made of cast iron as directed, with panels.

"The sills for the elevator door openings are to be special, and to have groove for sliding doors, to have nosing and beveled apron; and all are to be properly fastened.

"All necessary cutting, drilling, and tapping of iron and steel work that may be required by other contractors, is to be done by the Con tractor, as the Architect may direct." This may cause the contractor no little extra work. Some better specification than this should be made of it. If the architect in his design could not foresee the necessary cutting when comparing the plans for all con tractors, the steel contractor certainly would not be able to foresee how much he would be called upon to do, especially if he were working on the structural plans alone. This is another way of making the contractor re sponsible for errors and omissions, and is to him unfair.

"Guarantees—The following guarantees are to be delivered to the Architect: "1. Guarantee for all the skylight work for two years after the completion of the building.

"2. Guarantee for all the vault light work for two years after the completion of the building.

"3. Guarantee that the slate treads will not come loose for one year after completion." All of these guarantees are superfluous as given here.
