HOW ROTATIONS HELP OUT 23 



timothy to be sown with grain, but are hard to 

 keep in order. There are several cheap grass seed- 

 ing machines which scatter the seed by mechanical 

 means. They are satisfactory for seed that feed 

 through them readily, but it requires some patience 

 to regulate them properly, and the sower must 

 walk at a uniform rate or the seed will not be scat- 

 tered evenly. 



Seed of approximately the same size and weight 

 may be mixed before sowing. Very large seed 

 should never be mixed with small ones, or the small 

 seed will feed out first. If heavy seed is mixed 

 with light ones, even of the same size, the heavy 

 ones will feed out first, unless the mixture is kept 

 well stirred. In sowing such mixtures it is well to 

 put only a small amount of seed in the machine at 

 a time. 



THE GENTLE ART OF CULTIVATION 



How deep shall we cultivate ? That question has 

 been answered with quite a good deal of certainty. 

 At least a half hundred carefully planned and 

 executed experiments have, by their results, an- 

 swered in favor of shallow cultivation. Since then 

 we have heard much about this new idea in cul- 

 tivating the soil. But we are in danger of going 

 to the other extreme. Our fathers plowed corn; 

 they cultivated too deep. Some of us, perhaps, 

 cultivate too shallow; we get into trouble with 

 weeds; and because of our thin mulch, let the 

 water get away from the soil. 



In sections where there is much rain, the shallow 

 extreme may do ; but where moisture is demanded 

 — in the North, where the ground is frozen for so
