cies are generally low-growing hardy plants with clus- 

 ters of sessile, radical leaves and simple scapes bearing 

 a head of yellow or purple flowers in summer.

 Hemlock Spruce. Ornamental evergreen trees ol 

 pyramidal habit, with spreading, irregularly whorled, 

 much ramified branches clothed with small, linear,

the .Japanese speciis .m.l l'.i\u"- 

 liiiKiiin have proved hardy as far 

 north as Ontario. T. Hookeriana is 

 almost as hardy. T. Mertensiuna 

 and T. BruHoniana are more tender. 

 There are probably no more beautiful 

 hardy conifers tlian the Hemlocks, 

 and they must be ranked among the 

 most ornamental and useful trees for 

 park planting. They do not have the 

 stiff, formal appearance of many of 

 the conifers, but are graceful and 

 stately at the same time. T. Mer 



teitsiana is the most vigorous species and is more 

 graceful than the Canadian Hemlock, but tenderer. T. 

 Hookeriana is noticeable for its light bluish green foli- 

 age and the more narrow pyramidal habit. The Japanese 

 species have very handsome dark green glossy foliage, 

 but are of slow growth. T. Canadensis bears pruning 

 well and is well suited for tall hedges (see Gug. 2:289). 

 The other species will probably bear pruning well. The 

 Hemlocks are not very particular as to the soil, provided 

 it contains a sufficient amount o" 

 Tsugas are not difScult to transplant. Prop, by seeds 

 sown in spring and by grafting on T. Canadoisis. 

 The varieties and the Japanese species are also raised 

 from cuttings. See also Conifers, Abies and Picta for 

 cultivation. 



The genus contains 7 species, natives of N. America, 

 E. Asia and the Himalayas. Tsuga is closely allied to 

 Abies and Picea and differs little in the structure of the 

 fls. ; the cones are very similar to those of the lai-ch, but 

 the Ivs., though much like those of Abies in their out- 

 ward appearance, are very different in their internal 

 structure from all allied genera, since they have a 

 solitary resin-duct situated in the middle of the leaf 

 below the flbro-vascular bundle. The light, soft, brittle 

 and coarse-grained wood is not durable and not much 

 valued except that of T. Uertensiana , which is harder 

 and more durable, and that of T. Sieholdi, which is 

 esteemed in -Japan for its durability. The bark is rich 

 in tannin and th.at of T. Canadensis is extensively used 

 for tanning leather. 



Tsiiga Canadensis should be called "Hemlock Spruce," 

 but in common speech it is usually alluded to as "Hem- 

 lock." The "Hemlock" of the ancients is a poisonous 

 umbelliferous herb described in this work as Conium
