for this vast consumption. The reason is found in the fact that zinc-white is the only available white pigment that will not affect the color of any other pigment and is not itself susceptible to discoloration. Zinc-white is used by paintmanufacturers to increase the durability of their products, and by consumers on the score both of appearance and economy. Zinc-white in paint not only enhances its value as paint, but increases the ratio of volume to weight and consequently the covering capacity, and

the lower end of the slot to prevent swinging
of the fastener. When it is desired to open
the window the lower end of the fastener strip
is pulled outward to release it from the pin,
and the window is then pushed outward to
open position in the manner shown. As
the window is moved to open position the
fastener turns upon its pivot, the fastener slid-

than the slot to prevent detachment. The therefore the economy. This Company issues

Figure 2 illustrates the position of the improved "Invisible" Hanger applied upon the inside of each upper corner of the windowcasing and upon the outside of each upper corner of the sash. In fitting these hangers, the sash should be wedged up off the sill and close against the top of the window-casing, so that when it is hung, it will swing free of the sill and fit closely at the top.

Figure 4 shows how the improved fastener (Fig. 3) should be applied to the sash and window-frame, and how tightly it draws and holds the sash in. When closed, the

fasteners are made from steel, and are 10
inches long.

These patent goods are sold by all leading
jobbers, dealers and sash-manufacturers.

The price is very moderate and within the reach of all-in fact, the very lowest for the very best device of its nature.

ZINC-WHITE.

IT is hardly half a century since zinc-white was first introduced as a pigment in France. To-day in the United States alone the annual consumption is upwards of 40,000 tons. When one realizes how great a surface a ton of zincwhite in paint will cover, the figures seem almost incredible, and there must be good reasons

THE American Steel Hoop Company is going to put in steel bins at its Isabella Furnaces, Etna, Pa. This will require about 750 tons of steel, which will be furnished from one of the Pittsburgh plants of the American Bridge Company. The bins will be made in accordance with the design of Julian Kennedy, mechanical engineer.

PORTABLE SCHOOL-HOUSES.

WARMER, snugger places in all Boston it would be difficult to find than in the nine portable school-houses which, like a puzzle, can be taken to pieces, carried away, and put up in another place inside of ten days. If one did not know just how these houses were put together it would be excusable if he imagined that they might be as cold as the much-quoted barn. But no one believes this when it is understood that Architect Charles H. Brown put his best ideas into the subject, and that he wrought them all out in a manner as practical and scientific as though they were to be per. manent instead of temporary structures, with a location dependent entirely upon those school-yards where there is the greatest crush in school.

These nine school-houses are made upon honor and they are warranted to keep out the cold in a manner altogether effectual. The upper floor is of hard-pine boards seven-eighths of an inch thick. Underneath this floor there is a sheathing quilt. This so-called quilt is of heavy paper padded, not with ordinary cotton, but with something infinitely better-sea-weed
