pf the station about the first of August instead of much earlier, as it was assumed 

 they would do. The remedy suggested for this insecl is to wrap the base of each 



tree al t the last week in July for 18 in. from the ground in brown paper or 



newspaper, tying il with twine and wire. Aiter this the base of each trunk should 

 be mounded up 10 in. high around the paper covering. A.bou1 the lasl week in 

 October the paper is removed and the worms dug out.

On the effects of ringing, Leclerc im Sablon | Com pi. Rend. Acad. Sci | / 

 140 ( 1905), No. 28, pp. 1558 1555). The author ringed pears, quinces, and Japanese 

 euonymus, aged ."» to 4 years, on February 9 before vegetation started, and a second 

 lot May 8 after the first shoots had formed. At intervals of 2 months thereafter the 

 trees belonging to each of the 3 groups were harvested and analyzed 



The results obtained with pears are given in detail as regards roots, stem, and 

 leaves. The roots of the trees ringed in February contained more reserve material 

 than the control trees m.t ringed, while the stems contained less. Aiter April, how- 

 ever, as a result of assimilation by the leaves, the roots of the ringed trees were 

 much poorer in reserve material than those of the control tri 



On the whole the experiment is believed to show that toward the end of winter 



and the commencement of spring the reserve material goes from the root- to the 

 stem. From May to October the current of elaborated material is from t!.. 

 toward the roots. Like results were obtained with quinces and Japanese euonymus. 



Winter storage of nursery stock, M. Cooper ( Amer. Florist, .'■'• \ 1905 . No. 902, 

 pp. 329-888, figs. 8). — The author states that the winter storage of nursery stock has 

 become a permanently established feature of the nursery business. 



From his own investigations and the results of experimental work by others be 

 concludes that the best results in such houses will be obtained if they are maintained 

 at a uniform temperature of 28 to :;o" F. At this temperature very little ventilation 

 will he necessary; the loss of vitality through drying oul or shriveling is slight; and 

 there is a minimum tendency to mold and mildew. Packing material around the 

 root- and spraying with water would he unnecessary. 



Diagrams are given showing methods of construction of a suitable storage house 

 for nursery stock and suggestions made regarding the establishment of the refrigerat 

 ing apparatus. The experiences of a number of nurserymen with cold storageare 

 quoted. 



Forcing strawberries, ('. E. Hunk and .1. Craig [New York Cornell Sta. />'"/. .'■>'/. 

 pp. 5 14, fig*' '■ I. — This is the second report of the station on this subject I 8. R 

 i', p. 353). The various factors studied were varieties best adapted to forcing, time 

 required to mature the crop, the effects of varying temperatures, and economic 

 methods of handling the plant-. 



Nearly 100 American varieties, * French varieties, and 5 English forcing varieties 



have been forced in the greenhouse. Neither the English nor French varieties have 

 given satisfactory results. Experiments with American varieties indicate that the 

 midseasou varieties are preferable to either extra early or late varieties. The 3
