hydrastin, berberin, and canadin. The cultivation required is similar to 

 that of ginseng, and the plants are propagated by seed, by division of the 

 rhizome, or by root division. The crop matures in about three years, 

 and the yield should be over 1,500 lb. per acre of dried roots. It is 

 necessary to grow the plant in the shade, since it is at home in the woods 

 of the Eastern States from New York and Ontario southwards. — F. J. C.

Hybridising 1 Hollies. By F. W. Card (0 r .,S'..l. Exp. Stn. Rhode I. 

 Kept. 1903 ; p. 223). -Endeavours were made to cross Ilex glabra (a
