carbide, which is in the receptacle "P"; the gas thus generated is held
in the reservoir "G," and when sufficient pressure has been created is
forced out through the burner "B."

The lamp is small and compact; it is but four inches high, and yields a
beautiful bright light which will not blow out. When it is desired to
put the light out, the button "R" is pressed down, thus shutting off the
supply of water; this stops the generation of the gas, and the lamp soon
goes out.

"C. H.," Germantown, Pa., asks if the bicycles used in the Klondike have

". . . a book so beautiful, so valuable, and so _monumental_--whose new
appearance forms justly a 'Jubilee' event, in memory of its present
editor and publishers. In external beauty, in paper, type, presswork,
and binding, and all that belongs to solid and elegant book-making, the
volume is a fine specimen of German skill, good taste, and thoroughness.
And as a contribution to our lexicography, and its completeness and
