How to use a planting- plan, I. I i. Tabor I Gard. Mag. [X. F.], 8 | 1906), No. 8, 

 pp. 146, 147, '-hurt 1). A complete chart is given for planting a 50 by LOO ft. lot. 

 The plan shows the kind of trees, Bhrubs, and flowers to plant, just where each one 

 should be planted, an<l the method of transferring a planting plan to the ground. 



Blossoming- of fruit trees, L. B. Judson I Idaho Sta. Rpt. 1905, pp. ?S-82,charts 

 8). — The blossoming season of a large number of varieties of apples in different parte 

 of Edaho in 1904 5 are tabulated, as well as the blossoming season for l_ varieties of 

 pears and 5 varieties of peaches for the season of L905. 



On the winter injury of apple trees, \V. Stuart Vermont Sta. Rpt. 1905, pp. 

 299, S00, ph. ?). — A further note is given on the injury to apple trees during the win- 

 ter of L903 4, mentioned in an earlier report of the station I . 8. EL, 1 7, p. 249). The 

 winter-injured trees after blossoming and partially leafing out apparently stopped 

 growth and the unfolded leaves Bhriveled and died. Later in the season many of 

 the trees pushed ou1 into new growth, usually at the base of the scaffold limbs, or 

 somewhat higher up. 



Experiments were undertaken to see if the trees would not be benefited by prun- 

 ing. A number of eight-year-old Rhode Island Greenings were severely pruned 

 back, others less vigorously handled, and some not pruned at all. It was thought 

 that the severe pruning of the trees on which new growths were being pushed out 

 at the base of the limits would tend to throw the strength of the tree int" a few 

 branches, and thereby induce greater growth and a more shapely head. Tin- on-hard 

 was not given good cultivation. 



The growth made on the differently handled trees is shown in a series of illustra- 

 tions. "A careful study of this series of photographs affords little evidence that 

 pruning was beneficial." As a result of the investigations, the author recommends 

 that pruning operations be deferred to the latter part of the growing season or the 

 following spring, rather than immediately after such winter injury as noted in the 

 experiment. Severe pruning is inadvisable. 



Influence of stock on scion, W. Stuart (Vermont Sta. l!j>/. 1905, pp. 800-805). — 

 In 1899, 5 classes of plums were root grafted <>n 4 types of stocks. The stocks used 

 were Americana, Wayland, Marianna, and Peach, and the scions were Stoddard of 

 the Americana group, Green Gage of the Doinestica group, Chabot of the Japanese 

 group, Milton of the Wild (ioose group, and Newman of the Chicasaw group. 



The results secured with this combination of stocks ami varieties in Maryland 

 have been previously noted | 1-',. S. R., 14, p. 1069). The present report covers the 

 results secured in Vermont from 1900 to 1905. Tabulated results given in the report 

 show that !».'! per cent of the varieties on Americana roots lived, L00 per cent on Way- 

 land, St) per cent on Marianna, and 40 per cent on Peach. The average diameter of 

 the trunk of the trees produced on these different stocks is shown in the table below, 

 the measurements being made at the collar and 1 ft. above the collar:
