At the recent Brewery Exhibition, some of the machinery used in these
new maltings was shown in action by Messrs. H. Stopes & Co., together
with drawings of a malting constructed at Troyes for M. Bonnette under
M. Saladin's instructions. This malting is the third constructed for the
same firm, the others being at Nancy. That at Troyes we now illustrate.
We will not occupy space by a general description of the pneumatic
system, one great feature in which is the continuous manufacture of malt
throughout the year instead of only from five to eight months of the
year, as it will be gathered from the following description of the
Troyes malting:

[Illustration: FIG. 5.--ECHANGEUR, AXIAL SECTION.]

In our engravings, Figs. 1, 2, and 3, the letter A indicates the
germinating cases; B, Saladin's patent turning screws; C A, air
channels; D, passages; E R, main driving shafts; e, pulleys; F, metal
recesses to fit turning screws; G, elevators; H, trap doors; I, air
channels; J, openings to growing floor for air; K S, engines and fan
room; L N, fans, supply and exhaust; T, boiler; U, chimney; f, well. The
capacity of the malting is 130 qr. malt every day. This is equivalent to
an English house of 520 qr. steep. The whole space occupied is the area
necessary for kilns, malt and barley stores, engine and boiler house,
and fans. No additional area is required for germinating floors, as ten
germinating cases, A, are placed in the basement below the kilns and
stores. The building is of brick, with the internal walls below the
ground line resting upon cast iron columns and rolled joists. The
germinating cases, A A, are of iron; the bottoms are double. One of
perforated plate is placed 6 inches above the bottom. These plates admit
