planting". Oue pint of formalcleliyde will treat from 50 to 00 bushels. 

 The treatment may be modified by dipping the grain, one-half to one 

 bushel at a time, in a barrel or tub of the dilute solution. Drain, cover 

 for two liours, dry and the oats are ready for f>lanting. 



THE NEW CONCENTRATED FORMALDEHYDE TREATMENT. 



Use formaldehyde at the rate of one pint to 50 bushels of grain. For 

 smaller amounts of grain use correspondingly smaller amounts of 

 formaldehyde. It is unnecessary and unsafe to use more formaldehyde 

 than the amount recommended. Put the right amount of fresh formal- 

 dehyde just as it comes from the druggist, into a pint or quart hand 

 sprayer or atomizer and spray the grain as it is shoveled over and over. 

 The formaldehyde may be diluted two or three times to secure better 

 distribution. If the sprayer is kept close to the grain and if the treat- 

 ment is given in a room where there is a good draft, the penetrating 

 odor of the formaldehyde will give no discomfort. 



When the right amount of formaldehyde has been applied, shovel 

 the oats into a heap and cover for exactlj" four hours with a canvas 

 or blanket. 



The grain should then be spread out thinly for a thorough airing 

 in a warm place. Eake the grain over during this airing, then plant 

 at once. 



The formaldehyde treatment is cheap and easy. It is an efifective insurance against 



smut injury.
