mainder of the hole with water. After the water 

 has soaked away, finish filling the hole with soil 

 and firm it well with the feet If there is danger 

 of winds loosening the tree, set one or two stakes 

 and tie the tree to the stake with strips of soft 

 rag. They should be watched, and if the trunks 

 loosen an opening in the soil, tramp it tightly 

 against the tree. If possible irrigate the trees 

 from a canal or home water supply, but if this 

 cannot be done, try one of the following methods. 



TIN-CAN 

 IRRIGATION 

 TO START 



TREES 



When setting out the tree plant at a distance 

 of eight inches or a foot from the trunk, a five- 

 gallon oil can or other tin of like nature, putting- 

 it as deep as convenient in the soil. With a 

 sharp awl puncture a very small hole in the bot- 

 tom of the can. When the can is filled with 

 water it will insure the soil around the roots re- 

 maining moist for a long enough period to start 

 the growth of the tree. If water is convenient, 

 a piece of stovepipe set next to a tree and the 

 bottom half of it pounded full of manure, makes 

 an excellent method of supplying water and at 

 the same time stimulating with liquid plant 

 food. 



ARTIFICIAL 



BOOT 



PRESSURE 



Some years ago Professor Goff, of Wiscon- 

 sin, introduced a scheme of supplying artificial 

 root pressure to start newly-planted trees. Ex- 

 periments indicated that the method was very
