FORESTRY.

The white pine, G. PINCHOT and H. S. GRAVES (New York: The Century Co., 1896, pp. 102, pls. 6, figs. 6).—The authors have presented a very admirable study of the growth of the white pine, one of our most valuable timber trees. The motive which inspired the work was 'the desire to assist in making clear the real nature of forestry and in facilitating and hastening the general introduction of right methods of forest management." By means of tables and diagrams a mass of information is given which will enable one to ascertain the product per tree and per acre of standing pine and to predict its increase, rendering of easy calculation the relation between growth and expenses.

The deductions of the authors are based upon observations and measurements taken of first and second growth trees in the forests of Pennsylvania and northern New York at elevations ranging from a few hundred to about 2,000 ft. While the number of localities and measurements are somewhat limited, yet they are consid ered sufficient for the purpose at hand, and it is believed that the estimates will be found accurate for any region where white pine abounds.

DISEASES OF PLANTS.

Injurious fungi and insects (Jour. [British] Board Agr., 1896, No. 4, pp. 434-441, figs. 5).-Notes are given on the turnip mildew (Oïdium balsamii), a potato disease (Rhizoctonia violacea), washes for fruit trees, and fire blast of hops.

The turnip mildew is reported as having been especially prevalent during the summer of 1895, and several other plants are mentioned which are liable to attacks of Oïdium balsamii. The description and life history of the fungus are given and methods for its prevention suggested. Rapidly growing plants are not as subject to attack as stunted or drought-stricken ones. Charlock and other weeds on which the fungus grows should be eradicated, and turnips sprayed with a rather strong Bordeaux mixture. Cucumbers and vegetable marrows, which are also subject to attack, may be sprayed with Bordeaux mixture, 10 lbs. of copper sulphate to 100 gals. of water, care being taken to keep the fungicide from the flowers and fruit. In houses or frames powdered sulphur may also be used.

Illustrated notes are given of the potato disease caused by Rhizoctonia violacea. This disease made its appearance in stored potatoes in Surrey and Kent. The decay begins at the end of the tuber, extending downward. At first it may be seen by cutting the tuber, when, if present, a dark line is seen extending around the potato just under the skin. The disease can spread in stored potatoes, and whenever it appears all infected tubers should be sorted out and destroyed. Care should be taken that no diseased tubers be planted. So far the disease seems to be confined to supertuberated potatoes.

Various washes are described for application to fruit trees in order to prevent insect attacks, the principal ones being arsenite solutions, kerosene emulsions, and caustic soda or potash solutions.

Several diseases of hops are grouped together under the name "fire blast." The leaves of the plant become bronzed in color, and later dark brown spotted, after which they fall. The results are somewhat like those following attacks of the red spider, but none were found on the plants. At least one form of the disease is attributed to Heterosporium minutulum, but in many cases neither insect nor fungus pest was present in the more aggravated cases. This latter form is considered as of widest extent, and its cause is thought to have some connection with the soil. Applications of sulphur, cultivation, or manuring had no effect upon the disease. Heavy showers in August seemed to arrest it.

Some bacteria of the potato, E. ROZE (Compt. Rend., 122 (1896), No. 9, pp. 543-545).-The author calls attention to the potato scab fungus, Oöspora scabies, and describes 2 new species of Micrococcus which are said to cause definite diseases of the potato. The first of these, to which the name Micrococcus nuclei is given, is said to attack the potato, forming small, corky pits of about 0.5 cm. in diameter. These are first pale brown, becoming darker in time. It was found that the nuclei of the brown cells were changed in their appearance, while those in the apparently healthy adjacent cells were unchanged. On this account the specific name was given the organism. The Micrococcus is colorless, oval elliptical, by in size.

The second organism was found in Richter Imperator potato, where it forms in the parenchyma irregular spots 1 to 2 cm. in diameter, grayish in color, with a darker outline. If placed under a bell jar, the spots exude drops of a whitish color which by coalescence cover the surface. These are seen to be swarming with bacteria to which the name Micrococcus imperatoris has been given. The organism is colorless, oval elliptical, 2 by 1 μ in size. When more advanced, the grayish spots within the potato are resorbed, leaving cavities. Inoculations have been successfully made from cultures, the greatest success following inoculations made upon tubers which were afterwards buried in moist earth. So far this disease has not been observed upon any other variety than the one for which it is named.

Concerning the cause of the yellowing of the leaves of young fruit trees, J. HANAMANN (Jour. Landw., 43 (1895), No. 4, pp. 369– 378).—The author describes a yellowing of the foliage of young fruit trees in nurseries and gardens. It must be distinguished from the yellowing that follows a long period of drought, and its cause is attributed to impaired nutrition. Analysis of leaves from sound and diseased trees show that those from the diseased trees had a higher water content and a lower amount of organic substance than the others. The ash content of the "yellowed" leaves was higher in proportion to the organic dry substance than in the sound ones. Analyses of the pure ash of the yellow leaves showed an increase of the various substances entering into its composition, with the exception of lime, and of this there was a marked reduction, although analyses of the soil showed it to be calcareous in its composition.
