FORESTRY. 



Influence of spring frosts on the growth of oaks and beeches, 

 E. Griffon (Compt. Bend. Acad, Sci. Paris, 125 (1897), No. 15, pp. 

 548-550). — On May 18 a severe frost was experienced in France, the 

 temperature at Fontaiuebleau registering —8° C. (17.6° F). Great 

 injury was done to vineyards, forests, etc., and the author examined the 

 succeeding shoots of oaks and beeches to ascertain what effect the frost 

 had had on them. The earlier sprouts were killed, but in June "Others 

 appeared to take their places. These were abundant on the oaks, but 

 less so on the beeches, and their development was inferior to the 

 normal growth. The supporting and protective tissues were poorly 

 developed, and the secondary woody fibers and sclereuchyma of the 

 cortex were entirely undeveloped. In the leaves the pallisade paren- 

 chyma was much less differentiated than in the normal leaf.
