the pin gives way; the stan- 
dard, in consequence of its jointed 
connection to the frame, flies 
back, and a serious accident is 
prevented. I have endeavoured 
to illustrate this in the annexed 
sketch (Fig. 63). 
Brewster, Dodge, and Hiue, 
Peru City Plough Works, Peru, 
Illinois, make Walking Cultiva- 
tors both with iron and wood 
beams. These are very handy 
implements of light draft. The 
distinguishing features are a 
double or split pole, well secured to the bow of the axle. The standards are 
attached to the bow of the axle, and have sufficient play. Here we find a 
different arrangement to prevent break- 
age. The portion of the standard to 
which the hoe is fixed is attached to 
the main arm by, first, a steel pin, and 
secondly, a little lower down, by a 
wooden pin. Any violent collision causes 
the latter to break, and the hoe flies 
back, as seen in the accompanying 
drawing (Fig. 64). 
A good combination of a Cultivator 
and Broadcast Seeder was shown by 
Bean, Koft, Jarrett and Co. The stan- 
dards are split up at the end, so as to 
form attachments for the harrow teeth, 
which cover the seed that falls from the 
box. The standards are attached by chains to the main frame, and have 
considerable play. 
As a specimen of a One-horse Expanding Cultivator I may mention that of 
Bogers and Bisley. It is made of iron and steel (except the handles) ; it 
has three beams, the central one fixed, the others can be contracted or 
expanded by loosening a set screw ; the hoes, five in number, are made of 
cast steel with convex surfaces, which keep sharp by wear and tear.

When it is remembered that America is the home of cheese 
factories, and disputes with Sweden the introduction of butter 
factories, I expected to find this department more replete with 
statistical information than was the case ; but, with the exception 
of some tables as to the produce of the different States, there 
were no data that I met with giving a history of the rise and 
progress of this most important industry. The various com- 
panies, however, combined together to construct a butter and 
cheese factory, which was placed on the east of, and near to, the 
Agricultural Hall. It comprised a main building, 110 feet in
