more can be printed off in a few minutes.

The very general introduction of such a process has naturally been
delayed owing to the extra trouble involved in the first methods which
were suggested for applying it, and also, no doubt, on account of the
recent fashion for platinotype and bromide of silver prints. But as
soon as more convenient details for the making of pigmented gelatine
prints have been elaborated, the cheapness of the material and the
wonderful variety of the art shades and tints in which photographs can
be executed will give the gelatine processes an advantage in the
competition which it will be hopeless for other methods to challenge.

The daily newspapers of a few years hence will be vividly illustrated
with photographic pictures of the personages and the events of the
day. The gelatine photo-relief, already alluded to, will no doubt
afford the basis of the principal processes by which this will be
effected. Hitherto the chief drawback has been the difficulty of
imparting a suitable grain to the printing blocks made from these
reliefs; but this has been practically overcome by the use of sheets
of metallic foil previously impressed with the form of a
finely-engraved tint-block. The actual printing surface, of course,
consists of an electrotype or stereotype taken from this
metallic-grained photographic face.

For "high-art" printing on fine paper with the more expensive kinds of
ink, the half-tone zinco processes will doubtless maintain their
supremacy and gradually diminish the area within which lithographic
printing is required. In the case of newspaper work, however, where
haste in getting ready for the press is necessarily the prime
consideration, the flat and very slightly-indented surface of the
zinco block is found to be unsuited to the requirements. Flat blocks,
which require careful "overlaying" on the machine, waste too much time
for daily news work. Without going into technical details it may be
surmised in general terms that in the near future almost every
newspaper will contain, each day, one or more photo-illustrations of
events of the previous day or of the news which has come to hand from
a distance.

Type-setting by hand is, for newspaper purposes, being so rapidly
superseded, that only in the smaller towns and villages can it remain
for even a few years longer. But in the machines by which this
revolution has been effected, finality has been by no means reached.
