rough bark, and its living 1 branches all clustered near the top 

 of the tree, it presents always a sickly appearance. This can.- 

 not be recommended as an ornamental tree, neither is there 

 much value in the wood, which posesses a preponderance of 

 pitch and many knots. 



Pinus Strobus, L. White Pine. Another very common pine in 

 Pennsylvania, found often alone constituting- extensive pine 

 forests, from which large quantities of excellent lumber are 

 taken annually . In cultivation this is the favorite native pine. 

 It has a smooth bark, light green, slender leaves and usually 

 a thrifty growth. It was first cultivated in England in 1705, 

 and soon after large quantities were planted on English places. 

 It will never be superseded as an ornamental pine for this 

 latitude. Considerable space should be allotted to it to obtain 

 fine specimen trees. It is easily grown from fresh seed and 

 the seedlings bear transplanting very well while young. Too 

 often attempts are made to transplant specimens four and five 

 feet high from the woods, and these attempts result in fail- 

 ures ; one, two or three year old seedlings may be so handled, 

 or larger specimens from the nurseries. 



Taxus baccata, var. Canadensis, Gray. American Yew. A 

 straggling conifer, often called the Ground Hemlock, because 

 in foliage it closely resembles the hemlock. This dwarf ever- 

 green does well in cultivation if given a shaded situation. It 

 seldom grows higher than four feet. 



Tsuga Canadensis, Garr. Hemlock. The well-known and widely 

 extended conifer of our mountains and forests bordering on 

 streams. The lovers of evergreen trees are almost unanimous 

 in pronouncing this the most beautiful evergreen in cultiva- 

 tion. It is very graceful inhabit, retains a good green color 

 throughout the winter and maintains living branches all the 

 way to the ground, longer than any other coniferous tree we 

 grow. In most locations the tree is very dense, greatly con- 

 cealing the trunk and interior branches Excellent hedges are 

 made of this hemlock, and with proper pruning this may be 

 kept as low as three or four feet, green to the base at least 

 thirty years. The lumber is largely used as building material. 



Thuya occidentalis, L. American Arbor Vitce. The well-known 

 evergreen of cultivation. It is very common along streams 

 and in moist places of the north, extending southward into 

 Pennsylvania. It is called White Cedar in Canada and along
