. Bulletin. 1901-13. Agriculture; Agriculture. 18 EXPERIMENTS IN BLUEBERRY CULTURE. The man who put the blueberry seedlings in the ground, however, misunderstanding the directions sent him, filled in the holes in which he set the plants with alternate layers of soil and well-rotted stable manure. The writer ex- amined the plants on August 27, 1909, when they should have been either growing vigor- ously or, with mature foliage, ripening their wood for the winter. Instead they had lost nearly all their older leaves though still main- taining a feeble and spindling growth at the ends of the larger stems. The adjacent old bushes growing in precisely the same soil, ex- cept that it had not received the heavy appli- cation of manure, bore at the same time vigor- ous dark-green foliage and were ripening the wood of their stout twigs and laying down their flowering buds for the following year. The manured plants when dug up and exam- ined showed no new root growth whatever in the manured soil outside the old earth ball, and most of the roots on the surface of the ball itself were dead. Another experiment may be cited to show the injurious effect of heavy manuring. On December 22, 1908, six blueberry seedlings were transplanted into as many glass pots in a good blueberry soil, and six other seedlings were potted in the same manner, except that to each two parts of blue- berry -oil one part of well-rotted but un- leached cow manure v. as added.
