Spotting of Quince Fruit. J.C. Arthur. (Fourth Ann. Rep. 
N. Y. Agric. Exper. Station, p. 249; two figures.) 
The dark-colored spots-on quinces are caused by the growth 
of the fungus Morthiera Mespili, Fickl., var. Cydonia, C. and E. 
The mycelium colors the pulp brown for a short space below the 
surface, and the limits of its action are distinctly marked. The 
appearance and money value of the fruit are affected; no pre- 
ventive nor remedy is known. 
Tree Growth on the Plains. (Amer. Nat., xx., pp. 380, 381.) 
Prof. Bessey extracts from a recent paper by Robert W. 
Furnas on ‘‘ Tree Planting on the Plains,” a tabulated statement 
of the size reached by twenty-one different trees, varying from 
fourteen to twenty-five years of age. 
Tree Measurements. Prof. J. C. Smock. (Gard. Mon., xxviii., p. 111.) ” 
Prof. Smock contributes measurements of a number of forest 
trees growing near Holmdel, Monmouth Co., N. J., averaging 
thirty years old. The Red Maple has a circumference of 71 
inches; the American Elm, 60; the Tulip Tree, 63; the Locust, 
48; the American Larch, 42. -The comparative sizes which our 
trees may reach in a given number of years is a matter of great 
importance, and every accurate measurement made and recorded, 
is a useful contribution to the subject.

Western American Firs. C. S. Sargent. (Gard. Chron., xxv., p. 20.)

Arizona, New Mexico, etc., are but forms of a single species of 
great geographical range.
