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 recommended a cloudy or a showery day, or the evening, in order to avoid the effects 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 sunshine and the hottest weather, as they find no inconvenience 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 perfection of all the various parts, and in the preparation of the proper juice and the several products peculiar to the tree, as well as its wood and fruits. When all this is transpiring within its economy, the tree is said to be in its full flow of sap; at this stage the young tree is in the best condition for budding, but it continues also, if well cultivated, to grow by extension for a greater or shorter portion of the season, and this is essential to the success of the operation as already stated. After the perfecting of the crop of fruit, the main work of the tree seems to have been done for the year, and we often observe, particularly with the summer fruits, that the trees appear to go to rest after this period, and begin to cast their foliage. Now, to a certain extent, this is true of the young trees. The varieties that ripen their fruit early, make their growth in the nursery in the earlier portion of the summer, they stop growing, and their terminal bud is formed and is conspicuous at the top of the shoots. Very soon the supply of sap appears to be diminished, there is no longer so much activity in the circulation, the bark cleaves to the wood, it will no longer run, and the season of budding for those stocks has reached its terminus; hence the nurseryman must be upon the look-out for the condition of his trees. Fortunately, those species which have the shortest season, are also
