368 iEXPERIMEXTAL FARMS 



7-8 EDWARD VII., A. 1908i,'.33 



made a strong growth, -with the following exceptions, which were winter-killed: — 

 Viburnum lentago, Acer dasycarpum (seed from Winnipeg), Austrian Pine and Eed 

 Pine. 



Last spring (1906) a number of specially hardy Rose trees were sent from the 

 Central Experimental Farm, Ottawa, and set out in the Arboretum. These, with one 

 exception — Prau Karl Drushki, — did very well, making strong growth, and in most 

 cases blooming till late in the season. 



There were two each of the following varieties : — 



Souv. de Philemon Cochet, Belle Poitevine, 



Mercedes, Persian Yellow, 



Copper Austrian, HeterophyUa, 

 Delicata, • Calocarpa, 



Mrs. Anthony Waterer, Eoseraie de I'Hay, 



Rugosa Alba, Frau Karl Drushki, 



Yellow Capiicine, Madame Plantier, 



Five hundred plants of Sea Buckthorn were received from the Central Experi- 

 mental Farm, and planted for a hedge, and from the South Dakota Experiment Sta- 

 tion at Brookings, were sent 300 plants of Siberian Sandthorn, and 100 cuttings of 

 Niobe Willow. 



TREE SEEDS. 



Owing to frost killing the blossoms last spring, no seeds of the Native Maple 

 matured in 1906, and the usual distribution of these seeds cannot be made in 1907. 



As it is hoped that the 1907 crop will be good, providing a supply for the distribu- 

 tion of 1908, instructions for planting are repeated from my last report. 



PLANTING TREE SEEDS. 



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

 the Northwest, 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 lat« in October, or early in May. It is not safe to sow 

 all the supply of maple 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 J-inch in thick- 

 ness, while maple and ash should be covered 1 or Ij 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-fallowing old, make the 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. 



FRUIT TREES. 



PLANTING. i 



Last spring the Central Experimental Farm sent up a number of Russian Seed- 

 ling Apples, which were planted in Orchard No. 7, also over 200 Seedlings of Cross-
