are tied up, and enveloped loosely in a damp cloth, or in 

 moss, or fresh grass, to exclude them from the air. If 

 they should become wilted, they must not be put into 

 water, as this injures them; it is better to sprinkle the 

 cloth and tie them up tightly, or they may be restored by 

 burying them in moderately moist earth. 



The early gardeners were very particular as to the kind 

 of weather upon which to do their budding. They re- 

 commended a cloudy or a showery day, or the evening, in 

 order to avoid the eflfects of the hot sunshine. This might- 

 do in a small garden, where the operator could select his 

 opportunity to bud a 'few dozen stocks ; but even there, 

 wet weather should be avoided, rather than courted. But 

 in the large commercial nurseries, where tens of thousands 

 of buds are to be inserted, there can be no choice of 

 weather; indeed, many nurserymen prefer bright sun- 

 shine and the hottest weather, as they find no inconveni- 

 ence arising to the trees from this source. Some even 

 aver that their success is better under such circumstances, 

 and argue that the " pulp is richer." 



Most trees in their mature state make all their growth 

 by extension or elongation very early in the season, by 

 one push, as it were ; with the first unfolding of the leaves, 

 comes also the elongation of the twig that bears them. 

 In most adult trees in a state of nature, there is no further 

 growth in this way, but the internal changes of the sap 

 continue to be effected among the cells during the whole 

 period of their remaining in leaf, during which there is a 

 continual flow of crude sap absorbed by the roots, and 

 taken up into the organism of the tree to aid in the per- 

 fection of all the various parts, and in the preparation of
