attention and cultivation than any other tree. It is a tree that 

 is comparatively free from injurious insect attacks or from 

 fungous diseases until it has reached maturity. The demand 

 for the cottonwood lumber is good and will continue to in- 

 crease. Inasmuch as it is a lumber that can be used generally 

 on the farm, it merits a place in every farm woodlot for the 

 production of farm timber supplies. 



Bur Oak. 



The bur oak is native throughout the hardwood region of 

 the United States, and is found growing naturally throughout 

 the eastern half of Kansas. On favorable soil and in protected 

 locations it can be grown very successfully in the woodlots. 

 The wood of this species is hard, heavy, strong, and very 

 durable in contact with the soil when thoroughly seasoned. It 

 is a wood that can be used in almost every way on the farm, 

 makes excellent posts, framing timbers, bridge planks, railway 

 ties, and material for general repair purposes. The mature 

 trees are in demand for lumber purposes. It is one of the 

 valuable woods for factory uses, which are as follows :

Range and Habit of Growth. The bur oak grows in mixture 

 with the other hardwood species. It is seldom found growing 

 in pure stand. As a seedling it will endure considerable 

 shade, but it requires light from above to develop its best 

 form and to make its most rapid growth. When grown in 

 thick stands as saplings they develop tall, straight stems with 

 few limbs. By the time the trees reach middle age they de- 

 mand full light, and with the approach of maturity develop 

 broad, spreading crowns with massive trunks. The foliage of 

 the bur oak is very dense and allows but little light to strike the
