INTER-CROPPING OF CONTINUOUS CROPS 177 



For the purpose of sowing corn in this manner, 

 or even for drilling in* corn in the ordinary manner, 

 there is no better implement than the disc drill, one 

 of the finest inventions of the^ present age. Not only 

 does this implement sow the seed and completely 

 cover it in at the one operation, but in addition it 

 materially helps in the preparation of the seed bed. 



THE DISC DRILL THE BEST FOR THE PURPOSE 



Disc drills are made in various widths from 6 to 

 8 ft., and the sowing coulters, or shoots, are fitted 

 so as to sow in rows from 5 to 7 inches apart. For 

 general purposes, the disc drill fitted with the coulters 

 6 or 6 J inches apart is the best. 



With summer-sown corn, sown in rows about 12" 

 apart, as mentioned in the chapter on corn-growing, it 

 is necessary to graze down the crop before the advent 

 of winter. Otherwise, if the crop has made any- 

 thing of a luscious growth the frost will kill it. 

 This grazing down will generally be done in late 

 September and October. 



After grazing down sometime during early winter, 

 and whenever a favourable opportunity presents 

 itself, the cultivator should be run between the 

 rows of corn, the tines of the cultivator being 

 arranged so that they run in the centre of the row of 

 corn, and do not unduly disturb the roots of the grow- 

 ing crop. Sometimes it is possible to cultivate in this 

 manner immediately after grazing. At other times 

 the operation may have to be delayed until winter, or 

 even until spring. Then about April or early May 

 the crop may be grazed down a second time, or in a 

 backward season growth may not be sufficiently 

 advanced to admit of the second grazing down. 

 However, a second cultivation should be carried out
