THE ARBOKETUM. 



TLe trees and shrubs under observation in the Arboretum came through the win- 

 ter very vpell, and made a good start in the spring, owing to the early season. Though 

 the protection afforded by snow was comparatively light, through the light snowfall, 

 yet, as the winter was oi^ the whole mild, the trees did not kill back any more than 

 usual. During the summer, the abundant rains caused an extra strong growth in all 

 varieties, 



« 



The following additions were made to the Arboretum last spring, from the supply 

 of trces, «S;c., sent up from the Central Farm : — 



Syringa amurense, Populus angustifolia, 



Japan Tree Lilac, Viburnum opulus (Riding Mountains), 



Cornus sibirica variegata, Philadelphus nepaulensis, 

 Symphoricarpus (Gilbert Plains), Euonymus linearis. 



Viburnum lentago, Austrian Pine, 



Acer dasycarpum (Seed from Red Pine, 



Winnipeg), Scotch Pine. 



PLANTING TREE SEEDS. 



Many inquiries are made during the year as to the best way to grow tree seeds in 

 the Territories, where usually at the time they are sown, the soil is very dry. For sev- 

 eral seasons, little or no trouble has been experienced from this cause on the Experi- 

 mental Farm, while in some districts the weather has been very dry. 



Maple seeds can be sown late in October, or early in May. It is not safe to sow 

 all the supply of mapile seed in the fall, as very often germination takes place too early 

 in the spring, and frost kills the entire crop. 



Ash seed should be sown in October. Elm seed should be sown as soon as gathered 

 in June, though it sometimes succeeds if sown the following spring. 



Elm seed requires a very light covering of fine, moist soil, not over i-inch in thick- 

 ness, while maple and ash should be covered 1 or 1^ inches. 



Tree and shrub seeds should be sown in rows about 30 inches apart to permit 

 horse cultivation when considerable quantities are grown. In all cases the land should 

 be prepared the year preceding sowing, so as to have the soil as fine as possible. 

 Breaking and backsetting new land, and summer-fallov/ing old, make tlie best and 

 safest preparation. 



Trees should be transplanted when seedlings are 2 years old. When left until 3 or 

 4 years old, the trouble and expense are greatly increased. 



A large quantity of tree and shrub seedlings and seeds are available for next 

 spring's distribution. A list of a few of the best is given, with the uses to whjch thvy 

 are adapted.
