88 EVERGREENS. 



are little ones growing by the million which might be collected 

 and planted. They grow rapidly. The National Park is well 

 to the North, with an altitude of 8,000 feet and there is not 

 a month entirely free from frosty nights, and yet those trees, 

 under those uncongenial conditions, will often grow two feet 

 a year. At a, lower altitude, and under good conditions I am 

 sure they would be a success. I would earnestly urge the Ex- 

 periment Stations of all our northern states to give them a fair 

 trial; for I believe they will have a future in Minnesota and the 

 Dakotas. It would be an easy matter to try them In some 

 of our northern forests.
