 skins gave the following- results: One hundred pounds of air-dried bark

 ^4. tnoUissima and A. pyenantha bark tanned 112 and HH lbs., respec- 

 tivel3\ These results coincide approximateh' with tlie relative per-

Uses of wood pulp (Special U. S. Cortsulur Rpts., 19 [1900, pp.517). — A series of 

 reports are given on the uses and manufacture of wood pulp in various countries. 



The use of grape leaves for imparting special aromas to wines, N. 

 Passekini and P. Faxtechi [Slaz. Sper. Agr. lUil., SS (1900), Xo.5, pp. 436-440). — A 

 number of experiments are reported in which extracts of grape leaves from well- 

 known varieties were added to the fermenting must of wines in order to ascertain the 

 validity of the claim that the flavor and bouquet of wine could be influenced in such 

 a manner. So far as these experiments go, there seems to be nothing to indicate that 

 the aroma which characterizes certain varieties of Italian wines could be imparted to 

 other wines by the addition of extracts from the leaves.
