shares and cultivator teeth, attached to a frame, and mounted upon 

 two wheels, is so arranged that a driver sitting upon the seat 

 guides two horses, which straddle a row of corn or potatoes, and 

 work the ground upon each side. It is said to be a successful 

 cotton cultivator. It looks like a useful labor-saving implement. 



Brinkerhoff's Corx Shellers. 



Mr. Jacol) Brinkerhotf, Auburn, N. Y., exhibited one of his corn 

 shellers, which we have frequently commended as one of the best, 

 either for hand or horse power, yet invented. One man alone can 

 shell eighty bushels of corn a da}^ and it comes from the machine 

 clean and ready for the mill. Its action to-day was highly com- 

 mended by all who witnessed the operation. It was, however, 

 suggested that the machine be placed in the hands of some mem- 

 bers who will give it a practical test upon the farm, and report 

 results.

Dr. Peck exhibited specimens of a new invention, now coming 

 extensively into use in Boston, which bids fair to be of great use

 are adopting the improvement extensively. It is a cushion of 

 India rubber placed between the shoe and hoof, both cushion and 

 shoe being fastened hy the same nails. It is said to be not only a 

 preventive of dirt and gravel getting under the shoe, but entirely 

 prevents horses from baulking, and that the shoes will hold on 

 firmer and longer with than without the cushion.

Mr. Solon Robinson. — I am pleased to report that the committee 

 W'hich went out to Morris county, N. J., to witness the trial of a 

 new improvement of reaping machines, invented by F. Nishwitz, 

 Williamsburgh, N. Y., manufacturer of the Monitor Mowing 

 Machine, are perfectly satislied Avith the operation of this new 

 invention. 



We cannot speak in too high terms, and believe tliat we do not, 

 when we say that Mr. Nishwitz has discovered a method by which 

 any common mowing machine, Avith forward cutter-bar, can be 

 changed into a perfect self-raking reaper, in live minutes time, and 

 be operated without any apparent increase of power, and withal
