By a series of experiments upon the effect of gas upon different species of trees, by Messrs Spath and Meyer, in the botanical gardens in Berlin, it has been found that when the gas is brought into contact with the roots of trees for considerable length of time, in quantities however small, though some trees are able to withstand this influence longer than others, yet all must finally succumb, and will at last sicken and die. The influence is much less active during the winter, when the rootlets have become woody, than during the period of growth in the summer, when they are young and tender, and are therefore in a better condition to absorb the gas.

Fungus in California - D. J. Strent-zel, in the California Horticulturist, states, that two years ago, in the orchards along the Sacramento river, was first observed the extended growth of a new fungus, or lichen, on peach trees, covering the fruit in ash-colored blotches, and the ends of growing shoots in detached masses, spreading from a cottoney tuft of a growing germ. The leaves on the affected part drop off later in the season, and the end of the shoot generally dries up. The growth of the fruit is not apparently checked, but the thin-skinned varieties, on ripening, get a puckered up, pocky, disgusting appearance. The earliest varieties are most affected; the yellow, among them the Crawford, not so much. None was noticed on the Snow Peach.
