(_To the Editor of the Mirror._)
The world being supplied with books by _machinery_ is almost, literally,
a fact. Type-founding and stereotyping are, of course, mechanical
processes; and lately, Dr. Church, of Boston, invented a plan for
_composing_ (setting the types) by machinery; the sheets are printed by
steam; the paper is made by machinery; and pressed and beaten for binding
by a machine of very recent date. Little more remains to be done than to
write by machinery; and, to judge by many recent productions, a
_spinning-jenny_ would be the best engine for this purpose.
