226 THE XUT CULTURTST. 



Lake Tours, about three miles from the city, and is a 

 large tree. This specimen probably disappeared long 

 ago, and we have no means now of determining its ori- 

 gin or between what two species it was a hybrid. 



Recently Prof. C. S. Sargent has discovered other 

 hybrid walnuts in the neighborhood of Boston, and fig- 

 ured and described one in Garden and Forest for Oct. 

 31, 1894. He says: "My attention was first called to 

 the fact by observing that a tree which I had supposed 

 was a so-called English walnut (Juglans regia), in the 

 grounds connected with the Episcopal school of Harvard 

 college, at Cambridge, was not injured by the cold of the 

 severest winters, although Juglans regia generally suf- 

 fers from cold here, and rarely grows to a large size. 

 This individual is really a noble tree ; the trunk forks, 

 about five feet above the surface of the ground, into two 

 limbs, and girths, at the point where its diameter is 

 smallest, fifteen feet and two inches. The divisions of 

 the trunk spread slightly and form a wide, round-topped 

 head of pendulous branches of unusual symmetry and 

 beauty, and probably sixty to seventy feet high. A 

 closer examination of this tree showed that it was hardly 

 to be distinguished from Juglans regia in habit, in the 

 character of the bark, or in the form and coloring of the 

 leaves, and that the oblong nut, with its thick shell 

 deeply sculptured into narrow ridges, was the slightly 

 modified nut of our native butternut, Juglans regia. 

 Two other trees with the same peculiarities were after- 

 wards found. One is a large, widespreading specimen, 

 with a trunk diameter of four feet three inches about 

 two feet above the surface of the ground, and just below 

 the point where it divides into three large limbs. This 

 is on the grounds of Mr. Eben Bacon of Jamaica Plain, 

 and is supposed to have been planted between fifty 

 and sixty years ago. The other has a tall, straight 

 trunk, with a diameter of three feet one inch at three
