TStTGA (its Japanese name). Conlffiw. Hemlock. 

 Hemlock Si^klce. Ornamental ever^reeta trues of 

 pyramidal habit, with spreadinic. irregularly whurled, 

 much ramihtd branches clothed with small, liufar. 

 usually 'J-ranked leaves and small cones which are tisually 

 freely produced. The cont-s are only about 1 in. long 

 except in one species, which has cones two or three 

 times as large. T C'liii/Onisis is quite hardy north and 

 the Japanese species and 'T. Caro- 

 tin tan a have proved hardy as far 

 north as Ontario. T. Mc'keriti iia is 

 almost as hardy. 2\ Jltr/eu.sknta 

 and T. Brniioiuaaa are more tender. 

 There are pri:>baldy noniore beautiftil 

 hardy conifers than the Hemlocks, 

 and ihey 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. Mtr 



tensiaua- is the most vigorous species and is more 

 graceful than the Canadian Hemlock, but tenderer. T. 

 ffookeriana 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 Ong. 2:2891. 

 The other species will prof^ably bear pruning well. The 

 Hemlocks are not very particular as to the soil, provided 

 it contains a sufficient amount of constant nioisturc'. 

 Tsugas are not difficult to transplant. Pmp- ''>' seeds 

 sown in spring and by grafting on T. Canadensis. 

 The varieties and the Japanese species are also raised 

 from cuttings. See also Conifers, Abies and Picea for 

 cultivation. 



Tlie gentis 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 <if the 

 fls.; the cones are very similar to those of the landi. but 

 the Ivs., though mud) like those of Abies in tljeir out- 

 ward appearance, are very different in tln-ir internal 

 structure from all allii-d genera, since they have a 

 solitary resin-duct situated in the middle of the leaf 

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

 and coarse-grained wood is not durable and not much 

 valued except that of T. Merfensiana , whicJi is harder 

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

 esteemed in Japan for its durability. The bark is rich 

 in tannin and that of T. Canadensis is extensively used 

 for tanning leather. 



Tsuga Cnnndevsis 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 Conimn 

 Maculatum.
