THE PINE SUB-FAMILY. 191 



The beautiful specimen in the collection of the late John 

 Evans, at Radnor, near Philadelphia, is now 25 feet or up- 

 wards in height, makes a vigorous annual growth, and 

 with the exception of losing a portion of its leader in 

 an unusually severe winter a few years ago, has remained 

 entirely uninjured. 



This fine specimen stands on a gentle declivity facing 

 the south-west, and is growing in a light gravelly subsoil 

 that has proven too dry for some others of the Coniferae. 



The experience of cultivators in different sections of our 

 country has been so varied and so opposite in character 

 as to lead those interested in the success of this tree to in- 

 quire into this apparent contradiction ; and in every case 

 where we have been enabled to ascertain correctly, the 

 fault appears, not to have been in a few degrees farther 

 north or south, but to be in reality attributable to the nat- 

 ure of the soil and location. We therefore enjoin it upon 

 planters to select a cool, open, porous subsoil that is not 

 too rich, and endeavor to obtain a slight protection from 

 the northerly winds. Sargent's views on this point so ex- 

 actly coincide with our own, that we present them here : 

 "Plants with us in low, damp ground, suffer occasionally 

 in color, if not in loss of leader ; whilst those grown in 

 the shade, or on an exposed hillside, in poor, slaty soil, 

 succeed admirably." 



Nuttall remarks on the quality of the timber of this 

 species, that it is heavy and firm, with few knots, about as 

 yellow as that of the Yew, and not liable to warp, 

 which is quite different from the account given of it by 

 Dr. Parry. The latter says : " Wood of slow growth, but 

 very indifferent, inclined to warp and crack, turning red- 

 dish-brown in drying." 



Var. taxifolia, London. Syn. Tsuga Lindleyana, 

 Hoed. This is a Mexican variety found on the Real del 

 Monte Mountains at an elevation of from 8,000 to 9,000 

 feet. It is also occasionally met with in portions of Oregon,
