hogsheads or barrels with steam. It should be strained through an iron 

 strainer and applied to the trees as hot as possible. Certain precautions 

 are to be observed, (1) It is a winter wash (February or March best 

 season) and for deciduous trees only. (2) It is destructive to pumps and 

 nozzles, but this may be minimised by thorough washing with water after 

 use. (3) Clothing is ruined, and care should be taken of the eyes. Its 

 great advantage over other winter washes lies in its inexpensiveness, the 

 materials costing only 1 cent (f<J.)»per gallon, and in California the wash 

 is furnished and put on the trees for 5 cents (2Jd.) per gallon. — F. J. C. 



Lime upon Plant Growth, Influence of. By H. J. Wheeler and 

 G. E. Adams (U.S.A. Exp. Stn. Bhode I., Bull. 96; Aug. 1903; 4 

 figs.). — Experiments were carried out with various crops to ascertain the 

 influence upon them of lime in connection with nitrate of soda and 

 sulphate of ammonia. Lima Beans, Raspberry (Ohio Blackcap), and 

 Cranberries were injured by the addition of lime. Poppy, Zinnia, 

 Pumpkin, Squash (White Bush Scalloped), Currants, Asparagus, Pansy, 

 and Rhubarb were all improved by the addition of lime in connection with 

 nitrate of soda, while Grape (' Concord '), Blackberry, and Raspberry 

 (' Cuthbert ') gave the best results when sulphate of ammonia was used with 

 the lime. Tables are given showing the increase in the diameter of trees 

 when lime was used in connection with sulphate of ammonia and nitrate 

 of soda and when they were used alone. — F. J. C.

Lumbering- at Sewanee, Tennessee, Conservative. By John 



Foley {U.S.A. Dep. Agr. Bur. Forestry, Bull. 39). — The necessity for 

 strict supervision of felling and clearing timber has, unfortunately, until 

 lately received only a small share of attention, the result being that 

 indiscriminate cutting and a great waste of timber have been brought 

 about. Now, however, matters are entirely difte rent," for, with the rapid
