straddle over the edges of tlie timbers d, to whieh they are secured by set-screws. 
By thus forming these spindles a heavy axle is dispensed with, and the wheels can 
he adjusted hack and forth, so as to regulate the distance the edge of the floor shall 
travel from the ground. 
The sweeps of the reel may consist either of plain strips of wood, or the strips may 
have sheets of rubber or any other suitable material clamped in between or secured 
to them, as shown. 
Mr. Samuel Godard, of Marysvilie, Missouri, invented a machine for 
catching locusts (patent No. 101421, dated May 29, 1S77), of which we 
give the accompanying illustrations. 
PI. xi, Fig. 3, is apian view of the invention ; PI. xi, Fig. 4, is a ver- 
tical section of the same, and PL xi, Fig. 5, represents an eud view of 
the revolving frame. 
A machine somewhat like the above was invented by Mr. Fiuley E. 
Benson, of Walnut, Iowa (patent No. 184223, dated November 14, 
1876). PI. xi, Fig. 6, represents a plan view of the machine, and PI. 
xi, Fig. 7, a vertical section of the same. 
The machine invented by Mr. Dexter H. Hutchins, of Algona, Iowa 
(patent No. 187012, dated February 6, 1877), differs from all the others in 
having attached a contrivance for killing the insects by means of sul- 
phur fumes. PI. xn, Fig. 1, is a top view, and PI. xn, Fig. 2, shows 
a sectional view. 
Another contrivance was invented by Mr. Benjamin Sylvester, of St. 
Peter, Minnesota (patent No. 1887G0, dated March 27, 1877), of which 
drawings are herewith given. 
The " Hero 'Hopper-catcher," constructed by John Carlen, Berna- 
dotte, Nicollet County, Minnesota, is a simple bag with fan attachment, 
working somewhat on the same principle as the above. 
Most of these patent contrivances are open to the objection of extra 
cost and complication without extra efficiency, and the simpler devices 
will always retain their deservedly greater popularity. 
Mr. J. S. Belt, of the firm of Perkins & Belt, St. Paul, Minnesota, con- 
structed a simple sheet-iron pan, intended to hold the locusts without 
the aid of coal-tar. The machine consists of a sheet-iron platform with 
a front sweep of 8 feet, the back of which is elevated 7 inches and the 
front If inches, in the shape of a runner. Over the platform is a con- 
trivance that holds the locusts that hop upon the machine, and an 
effective cover prevents any from hopping over the grate. The imple- 
ment is easily pulled by ropes, and, with a 3-foot wing on each side, it 
sweeps over 14 feet of field. Its capacity is 3 bushels, and it can be 
emptied in 10 seconds. 
The following letter from Mr. Pennock Pusey, private secretary to 
Governor Pillsbury, expresses the opinion of those fully competent to 
judge of its value: 
This will he handed you hy Mr. J. E. Celt, who will exhihit a locust-machine, which 
strikes the governor and myself as the hest thing yet invented. It is on the same 
simple principle as that of the sheet-iron and tar dozer, hut dispenses wholly with
