STEAM ENGINE VALVES. By THOMAS HAWLEY. In considering the slide valve in its simple form with or without lap, we find there are certain limitations to its use as a valve that would give the best results.

A huge agave, or century plant, is now blooming at Auburn, N.Y. A few days ago the great plant became tinged with a delicate yellowish-white color, as its 4,000 buds began to develop into the full-blown flowers, whose penetrating fragrance, not unlike that of the pond lily, now attracts swarms of bees and other insects. The plant was purchased in 1837 by the owner, and was then twelve years old. For... more...
