GRAIN GROWING.

Peas may be successfully threshed with the 

 ordinary threshing machine by placing pulleys on 

 each end of the cylinder shaft double the circumfer- 

 ence of those ordinarily used. This will run the 

 cylinder at half speed, while the rest of the machin- 

 ery is on full speed. Take all the spikes out of the 

 concave except four. 



Because of the prevalence of the pea bug, or 

 weevil, many farmers have given up trying to grow 

 this valuable crop. In sections of the country 

 where the pea bug prevails, the seed should be 

 treated with carbon bisulphide to destroy the bugs. 

 This should be done early in the fall while the insects 

 are in the embryo state and before they have done 

 any material injury to the peas. 



The following method of treatment is very 

 effective and easily followed. Use an air-tight box 

 that will hold ten or twenty bushels. Fill the box 

 with peas and set a dish on top of the peas containing 

 one pound of carbon bisulphide, which is sufficient 

 to treat fifteen bushels, close the lid, making it as 

 air-tight as possible, and leave for three days. At 

 the end of the three days the carbon bisulphide will 

 have evaporated and penetrated all the peas in the 

 box, completely destroying the insect germs that 

 are in the peas without injuring the peas. Care 

 should be taken to keep away any flame, as the ma- 

 terial is very inflammable. If all the farmers in a 

 neighborhood would unite and treat their peas, it 

 would not be necessary to repeat this every year. 



As soon as the peas are taken off the land should 

 be plowed shallow with the two-furrow plow, rolled, 

 and immediately harrowed ; cultivated and harrowed 

 alternately until it is time to sow the fall wheat. 



The rotted sod, farm manure and pea stubble 

 will supply the nitrogen and other elements neces
