of Minnesota. "Raspberries carefully selected from 

 plants bearing berries of the best type for the 

 species in the regions around Lake Winnipeg and the 

 Riding Mountains in Canada for the purpose of secur- 

 ing the wild raspberry for breeding purposes in the 

 northern United States. This species grows abundantly 

 and is generally distributed in the localities visited 

 in Manitoba. It is quite similar in appearance in 

 its northern range to that of the northern part of 

 Minnesota where I have had the opportunity to observe 

 it quite extensively in the wilds, especially in the 

 region of the Red Lakes, Grand Rapids, Cloquet, Mille 

 Lac, etc. It seemed .from the preliminary survey of 

 the field that it would be best to visit localities on 

 the edge of the granite area extending in a northerly 

 direction about sixty miles east of Winnipeg, as well 

 as the region of the Riding Mountains. The granite 

 area was visited at points around Lac du Bonnet, the 

 Winnipeg River and the Pinawa River. From these 

 points on the margin of the granite area in the east 

 I proceeded to the west from Winnipeg to the Riding 

 Mountains. Here R. strigosus grew generally along ditches 

 and roads and in the burned-over areas of the foot- 

 hills. In the eastern region the raspberries were on 

 the whole bearing more abundantly than those in the 

 west at the Riding Mountains. The isothermal lines 

 extend considerably northward in this region so it 

 seems to me from the progress of the season and the 

 nature of the vegetation that perhaps all told the 

 selections in the east on the granite area were made 

 from stock subjected to harder weather conditions than 

 in the west. Of course, in this part of Canada when 

 winter sets in it is quite constant, and there is 

 generally snow enough to cover raspberries growing in 

 the wild. For this reason there may be an extension 

 of the species northward owing to its natural protec- 

 tion rather than its ability to withstand cold."
