it is preferable to use the cions as soon as possible after 

 cutting. Where winter conditions are severe enough to 

 cause injury cions should be collected in the fall, some- 

 time preceding the expected heavy freezes. In other 

 localities any time through the dormant season will answer. 

 The cions are clipped from the trees, tied up in bundles, 

 properly labelled and carried away to some convenient 

 storage place. They may be placed in a box, and covered 

 with sand, and set away in some cool moist place until 

 needed. They should be examined from time to time to see 

 that the sand does not become dry. The temperature ought 

 not to get above forty-five degrees as there will be danger of 

 the buds starting. If proper attention be given to mois- 

 ture and temperature cions may be kept all through the 

 dormant season without any appreciable loss of vitality.
