height for filling bags. By regulating one lever the vibration 
given to the feeding-trough is automatically varied. An 
advantage claimed for this mill is, that it can be run at different 
speeds, and effectually do its work — the speed recommended is 
320 revolutions ; but it will accomplish a corresponding amount 
of equal quality of work at 100 revolutions. The plates are 
made of cold-blast iron, and are exceedingly hard. Self-acting 
springs are attached to save injury from stones, hails, or any 
other hard substance passing through. 
George Hathaway, No. 1086, Shakespearian Churn. — This 
churn is entirely without beaters or other internal arrange- 
ments, consequently simple and easy to clean. 
The barrel is hung on the eccentric principle, with the idea of 
giving greater and continual concussion as the cream falls from 
end to end. The great novelty in the churn is the fitting with 
a circular hollow metal plate, which is attached to the bottom, 
forming a chamber to contain hot water (indispensable in cold 
weather) ; and as cream is required to be at a temperature of 
from 58 to 60 degrees, to be proper for churning, this arrange- 
ment entirely obviates other more troublesome processes, as the 
temperature of the contents of the churn can be raised in a 
short time by the use of hot water in this chamber. It is 
equally effective in hot weather by using cold water in the same 
manner. 
The bung, which is the whole of one end of the churn, is 
made of one piece of mahogany, and is forced into a metallic 
ring of angular shape, and flanged over with pressure without a 
screw or rivet, giving a very smooth surface, simple and easy to 
clean. This arrangement supersedes the original bung, which 
was heavy and complicated. 
Mr. Robert Maynardy No. 3304, Chaff-Cutter. — This raachine,^ 
named the " Mighty," is fitted with seven knives, and is on a 
similar principle to the chaff-cutter made by the same inventors 
witn six knives, complaint having been made that the latter 
was unequal to chaff fast enough to keep the thresher-shaker 
clear. The surface of the feed-rollers travels proportionately 
fast to make up for the other extra knife, so that the same 
sample is produced as in his other size ; the feed-box and 
mouth are also made wider. From trials made with this 
machine we were told that it is capable of chaffing all the straw 
from any threshing-machine — and from its apjiearance we are 
inclined to endorse this statement. An ingenious arrangement 
is made to sharpen the knives without the trouble and time 
of taking them off, as is usually the case. For this purpose a 
plate is attached, on which arc screwed a series of wide files 
about six inches long, making a plate of files. By means of
