successfully cultivated in the Northern States." During the trying 

 winter of 1903-1904 the Japanese Yew, entirely unprotected, was 

 not injured in the least. It grows quite rapidly and promises in 

 the course of years to assume the proportions of a tree. There 

 appear to be two distinct varieties in cultivation, one known as 

 T. cuspidata variety brevifolia and another with distinct fastigiate 

 spreading branches which is not as far as we are aware recognized 

 under any name. 



The Canadian Yew (T. Canadensis) commonly known under 

 the name of Ground Hemlock, a common native throughout the 

 Northern States and Canada in moist dense woods, is well adapted 

 to cultivation. Planted in exposed situations it assumes a very 

 different appearance from the natural condition in shade. We 

 propagate it from cuttings in large ciuantities for planting on moist 

 slopes, banks and ravines. 



The Japanese Ginkgo (G-inhgo hiloha), a deciduous conifer, has 

 shown great hardihood in the Northeastern States and grows to a 

 large size and attains mature beauty. Its usefulness as a street 

 tree has been shown in Washington, D. C. The Ginkgo in a young 

 state has a stiff, ungainly appearance, but when it attains a con- 

 siderable height and age it looks remarkably picturesque. In the 

 fall the leaves turn to a very beautiful light shade of yellow, and a 

 tree covered with these leaves is beautiful against a background of 

 evergreens. 



Discussion. 



John W. Duncan spoke appreciatively of the lecture but he did 

 not quite agree with jNIr. Dunbar's criticism of the Norway spruce. 

 He said that he thought he had convinced him of its beauty and 

 desirability after he had shown him the handsome specimens of 

 this tree on the lawn of the Hunnewell Estate at Wellesley. ISIr. 

 Duncan said he considered it one of our best conifers and that the 

 Retinisporas also were great favorites of his. 



William H. Spooner said he would like to inquire if a very dry 

 summer followed by a cold winter was not the primal cause of the 

 winter killing of some of the conifers. 



Mr. Dunbar replied that such conditions might have an injurious
