Page 28 - Further and more systematically conducted experiments are required in order to determine fully what preparation is most efficacious, at what season it is best to make the applications, "and the strength to which the solutions must be limited. Where "eau celeste.
Page 28 - Using one or the other of the above preparations, the following course of treatment is suggested : (1) In early spring, before the buds have commenced to expand, spray the trees, thoroughly with a solution of sulphate of iron, using 4 pounds of the iron sulphate to 4 gallons of water. (2) As soon as the fruit has set, apply the Bordeaux mixture or one of the modified preparations of eau celeste. (3) If the weather should be such as to favor the development of the "scab...

It is simple and easily prepared and is very strongly adherent to the foliage. Simple solutions of sulphate of copper ought not to be employed during the growing season as their use is almost certain to result in injury to the foliage. The Bordeaux mixture (see page 328) may be used at any time without fear of injury.

Page 87 - he had found in the tissues of the root, and of the old and young stems of diseased trees, an organism, classed with the bacteria, which is not known to occur elsewhere. This organism has been frequently obtained by method of cultures under circumstances which preclude the possibility of its coming from anything except the inner cells of the tree. He had it growing in artificial media, and it exhibited all the peculiarities of a pathogenic rather than a saprophytic microbe. It...
Page 32 - At this period of my investigation some unexpected and highly interesting phenomena occurred, which turned out to be of a very complicated nature, and the unravelling of which cost me much time and labour. After careful consideration of the subject, I have come to the conclusion, that the clearest mode of giving you an account of these will be to adhere nearly to the order in which I followed them out.
Page 33 - One other question has been raised, and it is that which I do not at present see my way to accept, that this is a form of Agaricus lacrymabundus, Fr. I have not recognised the "weeping gills," and for the time being will pass it by as an " open question." I must be permitted to relieve my mind a little in reference to three or four closely similar forms to each other which have hitherto borne distinctive names, but which I am beginning to think do not deserve that honour. This group includes, as...
Page 87 - Burrill intimated that he had found " in the tissues of the root and of the old and young stems of diseased trees an organism classed with the bacteria which is not known to occur elsewhere. This organism has been frequently obtained by method of cultures under circumstances which preclude the possibility of its coming from anything except the inner cells of the tree. He had it growing in .artificial media, and it exhibited all the peculiarities of a pathogenic rather than a saprophytic microbe.

Stem at first compact, at length spongy-soft within. Gills somewhat forked, with a few shorter ones intermixed, commonly attenuated at both ends, thin and normally narrow. III.
Page 88 - Pierce, a special agent sent to investigate the disease, states that yellow spots occur on the leaves, which showed no trace of insects or fungi. That " the peculiar appearance and location of these spots led to a careful study of the same, which resulted in finding bacteria-like bodies in large numbers, within the chlorophyllose cells of the spongy parenchyma immediately surrounding the spiral vessels supplying that region. After a long series of observations, made on material from various portions...
