How to Kill Poison Ivy. 



Spraying with arsenate of soda (one pound to twenty 

 gallons of water) will kill all vegetation. One applica- 

 tion, if the plants are young and tender, will do this. In 

 the middle of the summer, however, they should be cut 

 down first, and more than one application given. 



To Find the Number of Plants to the Acre. 



Divide the number of square feet in an acre, which 

 is 43,560 by the multiplied distance the plants are set 

 each way. For instance: Suppose the plants are set 

 two feet apart and the rows are four feet apart. Four 

 times two are eight; di\i.ding 43,560 by eight we have 

 5,445, the number of plants to the acre when set 2 feet by 

 4 feet. If set 5 by 1, there are 8,712 plants to the acre, 

 etc.
