flat heap and slightly covered with forest leaves. It is best to select a shel- 

 tered place for such heaps, as in a young- growth of timber or at the north 

 of a hedge. 



Planting stratified seeds in the spring should be given as careful atten- 

 tion as the process of stratification itself. Large seeds should be screened 

 out and dropped at proper intervals along trenches of suitable depths, and 

 immediately covered with fresh earth. Exposure to sun and wind for a 

 few hours after removing from stratification may cause the loss of Avhat 

 might have been a good stand of trees. Small, fine seeds may be scattered 

 with the sand along the furrow and lightly covered or tramped in.

Seedlings may be grown in rows, or the seeds may be sown broadcast, but 

 in all cases, except when the plants are to be budded instead of grafted, it is 

 not necessary to sow the seeds in rows having the desired distance of the 

 nursery row between them, as all root-grafted and crown-grafted trees, as 

 well as many budded trees, are transplanted once or twice before being 

 worked. In our own state it is believed that seedlings should always be 

 grown in rows instead of broadcast in seed beds. 



Root stalks — The nearest approach to the use of root stalks that falls 

 within the Avoi'k of the nurseryman is the propagation of blackberries from

root cuttings and root sprouts. This is not a case of true root-stalk propa- 

 gation, but an approach to it. A case of natural propagation by root stalks 

 is seen in .Johnson grass and the other couch or quack grasses shown in Fig. I.
