ities. What has been done, can be done, and 

 more is sure to be accomplished in the future. 

 The following lists should be important guides 

 to those who will plant. 



At Laramie, Wyoming, the following list of 

 trees are growing in the city : Cottonless Cotton- 

 wood, Native Black Oottonwood, Russian Wil- 

 low, White Willow, Native Balm of Gilead, 

 Quaking Aspen, Silver Poplar, Colorado Blue 

 Spruce, Native Pine, Douglas Spruce, Tartarian 

 Maple, Siberian Crab, Wealthy Apple, Dutch- 

 ess Apple. All are irrigated. Wind breaks are 

 necessary to make trees succeed. 



At Cheyenne, Wyoming, all the trees named 

 for Laramie are growing, and in addition we 

 have noted the following : Horse Chestnut, Car- 

 olina Poplar, Honey Locust, Elm, White Ash, 

 Eed Cedar, Box Elder. Wind breaks are nec- 

 essary. 



In Northern Colorado are grown all the trees 

 we have named for higher altitudes in Wyoming 

 and in addition a long list might be added. We 

 mention a few of the more desirable additions. 

 Here, as elsewhere in the West, the more hardy 

 C'ottonwoods, Willows and Poplars are first 

 choice for new planting. Any of this collection 

 of trees should grow as well at the lower alti- 

 tudes in Wyoming, Montana, Nevada, Idaho,
