auy respect ; therefore there w:is no deinuud for Kocky Mouutuiii 

 trees, but Professor Saroeiit said that if they were iu Englaud they 

 would eomniand a guinea apiece. Later ou they Avere distributed 

 to various poiuts arouud Boston, some l)eing sent to Fori'st Hills 

 Cemetery and the Bussey Institution, and some planted in private 

 grounds. They have served as object lessons in beauty of form, 

 color, and character, and have created a desire and demand for 

 specimen plants of those hnving the silvery green foliage. After 

 it was Avell known that the lieautiful evergreen trees of California 

 would not succeed in New England, full twenty years elapsed 

 before it was learned that the same species taken from their native 

 forests iu Colorado, or grown from seed brought from that region, 

 were hardy in the East. While either trees, or seeds from trees, 

 •of the same varieties grown upon the Pacific coast ranges in 

 California, uniformly failed here, both trees and seeds which 

 were carried from California to Englaud were growu successfully 

 tliere, but if brought from thence to New England they just as 

 uniformly failed. But those sixty-two trees before mentioned as 

 doing well in the Botanic Garden in Cambridge, were raised in 

 Englaud, from seed grown in Colorado, and were imported into 

 this country when quite small. This discovery, if not new, was 

 an important factor in leading to the present demand for Rocky 

 Mountain trees. Their number now in sight here can l>e counted 

 l)y hundreds of thousands, in seed-bed stock and larger growth. 

 Thus the Douglas Spruce, concolor, pungens, and Engelmcmni, are 

 l)ecoming more and more common in nui'series, and desirable iu 

 collections of trees, and their names are found easier to speak. 



F. L. Temple said that the most valuable sorts of new evergreen 

 trees in this latitude, are those we get from the region of which 

 Mr. Harrison had so eloquently spoken to us. Most of the 

 conifers of Europe and Asia are already well known to us, and we 

 know pretty well what can be expected of them here. We cauuot 

 expect much more of special value, from those sources, unless, it 

 may be, in the way of new varieties of the species which we 

 already have. He had cherished very great hopes of the future 

 usefulness of the Ficea pnngens iu this latitude, and had been 

 enthusiastic in its propagation, but, while the blue form iu the 

 young trees is wonderfully beautiful, it appears to be a fact that 

 none of the full grown trees, even in its native hal)itat, hold the 

 full blue color so attractive in the vounoer trees. The plain.
