THRASHING OPERATIONS. 



In Table XLIII the original data for those thrashing crews most 

 frequently reported are tabulated by thrashing from shock and by 

 thrashing from stack or barn, the averages being given for each crop. 

 Taking the reported output for each crew and crop as standards, 

 there is included in the table a scale of allowances for each departure 

 of one man and for each difference in yield of 1 bushel, together with 

 the range in the number of men found by experience to be reason- 

 ably adequate in each case. From analytical tables it was found that 

 increases in the crew were not attended with proportional increases 

 in the daily output of thrashed grain. In calculating the duty for 

 any crew other than those in the table it is therefore advisable, to re- 

 duce the result obtained for the larger crews from 5 to 10 per cent and 

 to increase the results computed for smaller crews in like proportion. 



In thrashing from stack or barn more than four horses are rarely 

 found necessary. In thrashing from the shock a horse for each man 

 is the rule. The length of cylinder used ranges from 18 to 44 inches, 

 the 36-inch length being in most general use, with the 32 inch second 

 in favor. Increased capacity is attended by increased output daily 

 when accompanied by adequate crews, the capacity of the larger 

 machines when properly fed being considerably in excess of the 

 ability of the average crew to deliver the grain to the machine. 

 Much larger crews are used in shock thrashing, but the amount done 

 per day and per man is about the same for crews of the same size. 

 The larger crews used in shock thrashing give larger quantities per 

 day, but the output per man and per horse decreases with increased 

 crew, thus adding to the thrashing cost per bushel. The thrashing 

 charge against clover and alfalfa is about 4 to 5 times that for 

 timothy, 15 to 20 times that for flax, 20 to 25 times that for wheat, 

 and 30 to 40 times that for oats.
