It is proper to say that, as the station was but recently established, most 

 of the trees and shrubs planted are very young, and more time will be 

 needed to test their hardiness. Enough, however, is already proved to 

 show that there are many trees and shrubs that may be safely planted on 

 the prairies in all parts of the state up to at least the 45th parallel. 



Most of the Russian willows and poplars are doing well, Populus Cer- 

 tinensis is particularly promising. Goat Willow is hardy. Wisconsin 

 Weeping Willow freezes back some. Salix Vitellina wintered without in- 

 jury last winter, although when younger it killed back to the ground each 

 year. Its bright orange-red limbs in winter make it very desirable to 

 brighten up winter shrubbery. Salix 14 A^or. seems to be the same as Salix 

 Vitellina. Populus 23 Riga seems to agree with Prof. Green's description 

 of Populus Wabski, and it, perhaps, is the same. • Populus Bolleana is a 

 fine tree quite distinct from the ordinary Silver-leaf Poplar. Young 

 trees of the Laurel-leaved willow were injured some last winter, but they 

 will doubtless do better as they get older. Salix Napoleonensis freezes 

 back every winter and does not seem to increase in hardiness with age. 



Colorado Blue Spruce, White Spruce and Balsam Fir are all doing well. 

 I have been unable to make White Pine grow here, and I doubt that any 

 one has succeeded with Norway Spruce here. Those who have planted 

 Black Spruce brought in by teams -from the swamps to the northeast of us 

 have all been disappointed. European Larch after growing for six or eight 

 years appears to fail. Dwarf Mountain Pine is extremely hardy and one 

 of our most promising evergreens. Our native Juniper is extremely hardy 

 too. All the lilacs that I have tried succeed and make themselves at 

 home. The new Japanese Tree Lilac seems to be as hardy as the others. 

 All of the bush honeysuckles do well. Our native Lonicera Sullivantii is 

 one of the best. Lonicera Gracilis and Lonicera Splendens from Prof. 

 Budd are doing finely. The Pbiladelphi are all good. 144 Vor. of 

 Prof. Budd is doing exceedingly well. The spiraeas need more moisture 

 than we are apt to get in western Minnesota. Spiraea Hypericifolia and 

 Spiraea Nobleana from Prof. Budd seem to be doing the best. The car- 

 aganas are all doing well. The common Yellow Flowering Currant is an 

 excellent shrub. Cornus Sanguinea from the nurseries seems to be the 

 same as our native cornel. Both do well. Lovett's Success Juneberry 

 promises well. Prof. Budd's Russian Snowball seems to be an improve- 

 ment on our common one. Golden Elder and Cut-leaf Elder freeze 

 back some but are doing pretty well. I become year by year more con- 

 vinced of the desirability of our native Viburnum (Virbunum Lentago) 

 for ornamental planting. It is, as it grows here, one of the finest shrubs 

 we have, but I do not find it in any of the nurserymen's lists.
