by Mr. Wm. Bearly, mining engineer, that twenty four head of 

 the most complete stamps could not reduce to powder more than 

 half the quantity of Cochran's machine in the same time, with the 

 application of equal power. In one of Cochran's machines, driven 

 by a band seven inclies wide, at the rate of six hundred teet per- 

 minute, 14,160 pounds accurately weighed was perfectly pulver 

 ized in one hour and fifty minutes. a. c. 



MOWING AND REAPING MACHINES. 



The competitors in this department of agricultural machinery 

 numbered nine. It is to be regretted that the managers could 

 not have had an opportunity of testing practically the merits of 

 these different machines; the lateness of the season, however, 

 rendered such a test impossible. Consequently, the judges to 

 whom they were submitted had very little save an examination 

 of the machines to guide them in coming to any satisfactory con- 

 clusion as to their respective merits. The judges say: "The 

 machines submitted to us are of two distinct classes, viz : one for 

 mowing alone, the others combine the operation of mov;ing and 

 reaping. The machine exhibited by W. F. Ketchum, of Buffalo, 

 for mowing, from our own examination, and from the evidence 

 presented to us, we are of opinion, is a valuable machine. The 

 maker of it has been the pioneer in the introduction of mowing 

 macldnes, and has spent many years in overcoming obstacles to 

 its success; we recommend to it the highest award of the Insti- 

 tute, as a mowing machine. Of those which combine reaping 

 and mowing, there are six, and one model. They all show a 

 very high order of merit, and some of them have done good ser- 

 vice in both kinds of work ; one of them is entirely new, and two 

 of them have not been in a condition for us to estimate what they 

 might do. Under these circumstances, your committee have 

 thought they could not give such an opinion of their comparative 

 merits as would be creditable to the Institute or just to the ex- 

 hibitors, and therefore suggest that this statement be published 

 in lieu of awarding distinctive premiums." We will add here 

 the names of all the exhibitors : W. F. Ketchum, Buffalo, mow-
