Implement Skoio at Bury St. Edmund's. 603 



hindrance from rain would be avoided. We further think that the 

 trials of food preparing machinery would be more satisfactory 

 under cover. 



Some objection was taken to the validity of the thrashing 

 trials, not by exhibitors, but observers, on the ground that such 

 important decisions demanded a much larger trial, that instead 

 of 100 sheaves and 10 minutes, each machine should have set 

 down to half a day's work, and then the results would have been 

 of value ; but would this be so ? we think not ; every fact con- 

 nected with the working powers of the machine was as clearly 

 visible In the run for 10 minutes as In 10 hours, and each exhibitor 

 had been previously allowed ample opportunities to adjust the 

 various portions of his machine, according to the condition of 

 the corn. 



It is to be regretted that no premium was offered for Straw 

 Elevators In connexion with thrashing machine trials; the diffi- 

 culty of obtaining hands is Increasing every year, and certainly 

 the Elevator does the work of two men ; hitherto the price has 

 been too great considering the simplicity of the apparatus ; we 

 are glad to see that both Messrs. Hayes and Son, and Amies 

 and Barford, have somewhat reduced their prices, though there 

 Is room for further alteration. We hope to see these machines 

 sold at 30/. The power consumed by the best is very small, 

 probably varying from ^ to ^ of a horse power. 



Beport on Power-driven Chaff Cutters, Mills, &c. 



The Implements tried by us were all well adapted to be driven by Steam, or 

 Horse Power, viz. : — Chaff Cutters ; Grinding Mills, with stone grinders for 

 grinding agricultural produce into meal ; Grinding Mills, with metal grinders 

 for grinding agricultural produce for feeding purposes ; Linseed and Corn 

 Crushers ; Oilcake Breakers for large and small cake ; Bone Mills ; lioo 

 Pulpers. 



Chaff Cotters. We had sixteen for trial, and we gave each machine 

 one cwt. of very dry rough wheat straw for the first, and 70 lbs. of rough 

 hay to a few of the best machines for a second trial. See Table I. 



Gbixdixg Mills, with Stone Gbixdees. We had eight for trial, we gave 

 each mill some barley for a preliminary trial to adjust the stones, then 5G lbs., 

 and took time, &c., as below. See Table II. 



Grixdixg Mills, with Metal Grinders. We tried eight, our rule was to 

 give to each mill h cwt. of Indian corn, then ^ cwt. of barley. We made 

 two exceptions ; to one mill, because of the superiority of its performance, we 

 gave ^ cwt. of wheat and j cwt. of linseed, all of which it did equally well 

 See Table III. 



Linseed and Corn Crushers. We tried ten with 28 lbs. of linseed, and 

 84 lbs. of oats each. See Table IV. 



Oil Cake Breakers. Sixteen were tried with h cwt. to each machine for 

 breaking both fine and coarse. The time and power was taken while breakino- 

 the cake fine. See Table V. 



Bone and Bone Dust Mills. We tried only four, three of which worked 

 remarkably well. See Table VI. 



Boot Pulpers. Twelve tried, each with 1 cwt. of mangold. See Table VII.
