cording to the nature of the ground. 

 Mulch in summer with an inch or two 

 of leaf-mould or manure to prevent exces- 

 sive evaporation ; and whatever manure 

 is used, it must be well decayed. The 

 young plants should be planted in spring, 

 the roots being inserted 6 or 8 in. in the

soil and well watered. The Flame Nas- 

 turtium is best where the shoots may 

 ramble among the spray of shrubs, Ferns, 

 or trailers, but as it must be placed on a 

 cleared spot, it is well to put a few 

 branchlets over the roots for the young 

 shoots to crawl over. It is much better 

 to let them have their own wild way 

 than to resort to any staking or support, 

 except that of other subjects growing near. 

 Division or seed. Seeds should be sown 

 as soon as ripe, in a pan or box, in light 

 loam, leaf-mould, and sand. Place in a 

 pit or a frame, and keep the soil moist, 

 but not wet, until the plants make their 

 appearance in spring. The careful divi- 



sion of the old roots is, however, much 

 the best way to propagate. 



T. tuberosum. A distinct and beauti- 

 ful tuberous-rooted climber from Peru r 

 with slender stems 2 to 4 ft. high, and in 

 summer a profusion of showy scarlet and 

 yellow flowers on slender stalks. It 

 should be grown in open spots in the 

 poorest of soils, with its branches sup- 

 ported or allowed to trail along the 

 ground. As it is not hardy in all soils, 

 lift the tubers in autumn, store in a dry 

 place, and plant out in spring. 



TSUGA (Hemlock Spruce}. A dis- 

 tinct and graceful group of evergreen 

 cone-bearing trees, remarkable for their 

 fine form of leaf and graceful toss of 

 branchlet, and also in their own country 

 at least for picturesque and often stately 

 form. 



The one best known in Britain, so far,, 

 is the Canadian Hemlock Spruce, a tree 

 of proved hardiness in our country, 

 but rarely showing the dignity of form it 

 does in its own, probably from the use of 

 cutting plants. No tree of the pine race 

 should be planted in any form but that of 

 healthy seedlings. The splendid forms 

 of these trees so promising for our

country, coming as they do from moist 

 cool regions, will be best secured by 

 taking any necessary care to securing 

 healthy seedling trees, never large ones. 



The Japanese and Indian species of 

 this family, T. Sieboldi, Brunoniana, and 

 diversifolia are not proved to be of such
