and plenty of light increases it remarkably. It has so far taken on 

 a cleaner and straighter form than most cottonwoods, and the 

 wood seems to be denser and of a little better quality. 



Not enough experiments have been made with this tree for us 

 to know anything definite in regard to the ultimate use of the 

 tree or of the wood, but the trials which have already been made 

 speak well for it. Its family name is the .only thing against it.

Dahlia tubers should be dug immediately after the first heavy 

 frost, and the stems cut off about three inches above the tuber. 

 Store them in a cool, dry, dark cellar. A good way is to place them 

 On the cellar floor and cover them well with slightly moist sand or 

 soil, allowing it to shake down among the roots. Where only a few 

 tubers are to be kept, they may be put in a small box and treated 

 in the same manner. A piece of heavy paper fastened to each 

 root will serve to distinguish varieties. If not allowed to get wet, 

 the dahlias will keep in good condition until planting time.
