several parts of Cundlnamarca, and cultivated in the

Notes on Behavior of Previous Introductions, 
Mrs. Ida Toepfer, Warren, Ohio, in a letter re- 
ceived September 27, 1920, writes: 
"The English walnut , Juglans regia , S.P.I. No. 44 200), 
sent me 3 years ago, I kept in a pot the first year, 
and in a box in the cellar all the next winter. Las t 
spring I set it out; in the fall I put over it ^ n 
open barrel filled with leaves, and with a V-shaped 
cover. The plant came through the severe winter of 
1917-18, in excellent condition and is now a large 
tree. In another year I think the tree will be winter - 
hardy with a heavy mulch over the roots."
