Zinc, like copper, is again being urged upon the public by the manufacturers since the war demand is over. Zinc spouts are usually made from No. 11 zinc gauge, which is equal in thickness to No. 24 steel gauge.
There is hardly any need to mention the durable qualities of copper, zinc, or lead. Wherever the cost permits, one cannot deny that materials of such durable nature are the proper ones to use.

TYPES OF WOODEN-FRAME CONSTRUCTION
Types Explained
BRACED-FRAME
There are no sharp distinctions between the various types of wooden frame construction. But in order to classify certain tendencies, we will arbitrarily define four types. To these we will give the names of [braced-frame], [balloon-frame], [combination-frame], and [platform-frame].
The braced-frame is the oldest type, and originated in Colonial days in New England. It was developed under the influence of a tradition of heavy, European half-timber construction, and also nourished by the abundance of wood directly at hand. The fact that nails were not made, except by hand, urged the carpenters to use methods of fastening which required as few as possible. Because of these factors, then, certain definite characteristics of this type of wooden frame construction manifest themselves in the use of timbers, far larger than necessary for safety, and joints consisting of mortises and tenons.
