leaf mold or fresh, moist leaves are used for this purpose. 

 Where only small quantities are cared for, boxes are generally 

 used, which are lett out doors in winter; but where large quanti- 

 ties of large seeds like 

 those of the peach and 

 black walnut are used, they 

 are often mixed in pits on 

 the surface of the ground 

 and covered with sod. 



Apple seed is gener- 

 ally kept dry during the 

 winter and moistened and 

 frozen in the spring before 

 sowing, but may be stored over winter by stratification with ex- 

 cellent results. In the case of a few plants the seed will start 

 at once if stratified. In such cases dry the seed and do not sow 

 until spring. However, it is a good plan to mix it with damp 

 sand in the latter part of winter for a few weeks, after which it 

 may be frozen before being sown.

Propagation by Offsets. 



(a) The strawberry and red raspberry, American plum, Mo- 

 rello cherry and some other fruits may be grown by taking off 

 sprouts that come up from the roots. Such sprouts are termed 

 "offsets," or suckers. 



(b) Offsets arc best removed in autumn or in the spring. 

 In removing tlicm, it is important to set a portion of the main
