From Robert Manning, Secretary. We learn from that excellent report that rose culture seems to be growing in popular estimation in Massachusetts. $3,050 was the sum appropriated for premiums for the season. The papers and discussions refer to the taste for ornamental trees, which, the general remarks of the speakers indicated, did not grow near as fast as the ability of modern nurserymen to supply the want. Apple and pear culture seemed to indicate much the same. There are numerous varieties in existence far better than many which are popular. The great want seems not so much the encouragement of new varieties, as better means of making known the great number of good things which we already have. Flower culture, especially hardy flower culture, was freely discussed, and an immense number of good things pointed out as suitable for the latitude of Boston. An interesting paper on the yellows in the peach is by Prof. Penhallow. He found fungi at every stage of the disease, and described the species he found; but the discussion which followed showed that Prof. Penhallow's able paper had not the slightest effect on the minds of those who listened in inducing them to believe that the yellows was caused by fungus.

Indeed Dr-Goessmann, who immediately followed, remarked that "the disease may be due to atmospheric influences; on a sultry day, when evaporation cannot be carried on, stagnation may result and cause disease." It would be just as well to show, by experiments, that there is no evaporation on a sultry day, as to rise in a public meeting and say it "may be" so. It is, however, but justice to say that Prof. Penhallow's paper only deals with what he found after the disease' 1 appeared. There is no doubt but the fungus, which.causes the disease, is at work for a year before there is any evidence afforded by the appearances on the tree, and that this disease can be communicated by digging up a mass of fungus-infested roots, and placing it in the ground about a healthy tree. This evidence, already given in our pages, is worth more as indicating the actual fungus origin of the disease than any microscopical examination can be.
