No. 151. liotary Harrow. — New York Harrow Association, 35 

 and 37 Park Place, New York. 



Is a rotary harrow, pulverizer and grain coverer ; we think this 

 harrow, worthy of the first premium ; having had considerable experi- 

 ence in its use, we feel fully satisfied in saying that it meets the want 

 of the farmer better than any other brought to our notice, its rotating 

 motion keeps it from clogging, covers the grain admirably, levels the 

 ground and pulverizes the soil to perfection, it wuU clear itself from 

 any stone or stump upon which the teeth may happen to catch ; in our 

 estimation, once harrowing with this harrow, is as effective as twice 

 harrowing with any other we have seen in operation ; we can con»ci- 

 entiously recommend it for general use among farmers, it is adapted 

 to all Jvinds of ground, it is cheap, substantial and answers every pur- 

 pose. Too much cannot be said in its faror. 



No. Y36. Cylinder Flow.—R. H. Allen & Co., 191 "Water street, 

 New York. 



K^Two plows on same beam, almost indentical with the double Michi- 

 gan plow, used for turning sod and subsoiling at the same time. An 

 excellent plow of the kind, worthy of a diploma. 



No. 416. WiUicnnson''s Whiffie-trees for Douhh Teams. — Benjamin 

 Haskell, 190 Duane street, New York. 



"Whiffle-trees for double teams and heavy work, consist of a heavy 

 bar, sprung and steam bent ; at the center is hung a friction roller or 

 pulley through which a chain passes ; to the ends of this chain the inside 

 traces are connected ; in this manner the draft is equalized. Its 

 advantages are simplicity, durability, its equalization of draft, and 

 great strength. In our estimation it deserves the first premium.

No. 651. Mowing Machine {Buclccye). — Adriance, Piatt & Co., 

 165 Greenwich street. New York. 



This machine has in all probability given more universal satisfac- 

 tion than any other with which we have had any experience, 

 although the vast improvement made in the construction of other 

 iriowers is rapidly bringing them into favor. Even now they threaten 

 to become successful competitors. It is next to impossible for us, as 

 a committee, to pass judgment upon the relative merits of machines 

 not in operation that possess so many good points, by a simple exami- 

 nation. The only true means of deciding is to give them an oppor- 

 tunity of demonstrating their special claims of superiority under
