bottom. The six sails themselves have each an area of about 25 square feet, 
and as they were slipped in between the arms with a 4-inch bolt at the end 
board, and the others with a 3-inch nail through the arms | and boards, they 
were very securely fixed. If, in a very exposed position, this mill should have 
a tendency to go too fast, Mr. Stephens suggests a door or slide in the casing 
in preference to any brake arrangement. These mills should be set so as to 
face the prevailing winds. 
The method of making the arms for the wheel is to get (for up to a 20-foot 
wheel) pieces of 3 inches by 13-inch hardwood, and bolt them together, the hole 
for the axle being bored slightly smaller than the axle, so as to cramp on it 
when pe bolts are screwed up with pieces of batten to keep the arms equally 
divided. Py 
A USEFUL GATE CATCH. 
Hunting men know a little of the trouble experienced in opening gates, 
which somehow seem to be devised with the object of giving the maximum 
of trouble to the followers of the “sport of kings.” One of the latest and 
most useful gate catches is called the “ Eckby gate catch,” which has been seen 
at shows. The accompanying illustration explains the action of this catch, 
which is perfectly automatic, and does not fail.to receive the gate when it 
swings to the post. Having no springs, it is not likely to get out of order. 
Tt is claimed that an animal cannot possibiy open the gate secured thus, and, 
of course, the rider can open and close the gate without dismounting. Fixing 
is performed without much effort, no mortice-head requiring to be cut in the 
head of the gate, no sawing or cutting of the gatepost being required, and no 
blocks of wood: necessary for nailing to the post. ‘The invention, which has 
earned the approval of hunting men, is made by the Eckby Patent Gate Catch 
Company, 120 Edmund street, Birmingham.— Farmer and Stockbreeder,
