water gives a supply of ice that is convenient, 

 mulching bv placing lumps of ice around the 

 tree has given most excellent results. This ice 

 keeps the tree dormant, in a measure preventing 

 the swelling of the buds too early in the spring, 

 as well as keeping the soil from drying out. 

 Some l^orthern fruit growers are practicing 

 using the ice mulch and testify to its efficiency. 



KIND OF 

 TREES TO 

 PIAWT 



The list of trees for general planting is a 

 short one. In favorable locations and with pro- 

 tection a large variety of trees • succeed. In 

 towns and cities where there is protection af- 

 forded by many bviilding's, where the waAer sup- 

 ply is always available and the grower can give 

 much attention to his trees, j)ractically all the 

 varieties that grow in like latitudes elsewhere 

 will thrive. A good example of this may be 

 cited in the trees of Denver, where the long list 

 of varieties includes everything from the oak, 

 linden, chestnut, walnut, horse-chestnut, etc., 

 down to the ever-j)resent and most hardy cotton- 

 wood.
