Of more than 300 "Osband Summer" which I grafted on the Anger quince successfully, one remains, and this one was transplanted after they had fruited in a clay soil, to the same sort of soil between "the old standard" and a stable, both of which have occupied the same locality and within twenty yards, during much more than fifty years of my own observation--this "Osband Summer" flourishes. It has borne fruit in its present site, but grew so rapidly last year that the blossoms aborted thus illustrating the large proportion of vital force necessary to the production of fruit, as the site has a perennial supply of manure from the old stable. A number of standard trees, of the same variety, developed beautifully until they attained twenty or thirty feet, but then succumbed to the blight, after the first effort at fruiting. So also the Beurre Clairgean etc., etc. Their exposure to the same influences, and their growth during several years did not occasion the blight, but the debility which must inevitably attend fruiting seems the most prolific cause. All the phenomena of pear blight can be accounted for, and we are greatly encouraged in protecting the trees therefrom if, we assume, it is only the result of weakness and deficient vitality; if so, as in epidemics, all the pear trees may be poisoned or ergotized, but only the weakest succumb; and perhaps this debility may be confined to one limb. The practical value of this view is manifest, as it is impracticable to avoid using the same knife, and remove every blighted leaf from the orchard. Moreover, if the limb is a large one, its prompt removal shocks the vitality of the whole tree[1] and thus renders other parts more vulnerable. On the contrary view, the limb may be allowed to drop by natural process, precisely as all trees in a forest shed their lower limbs, leaving hardly a cicatrice or scar, and this may be insured at any season by a cord of hemp twine, firmly bound around the limb. The inevitable strangulation, and the healing of the stump (without the mycelium of fungi which the knife or saw inevitably propagates by exposing a denuded surface, if not more directly) proceed more rapidly than the natural slough of limbs by starvation. Moreover the fruit may mature on such limbs during their strangulation, as this may not be perfected before the subsequent winter. The next practical result of my view is the fundamental importance of all those means which are calculated to husband the vital force of the tree during its first effort to fruit; one of these is the use of a soil that will not produce more than twenty bushels of corn without manure, thus a large proportion of the setts will be aborted, but one half of what remains should be removed, and subsequently the area beneath the limbs should have a wheelbarrow of good compost.
