centage of them have the very bright colors which are so much 

 sought after. 



Rosa rugosa is doing well. This is a grand rose, and when 

 given plenty of root room and light and air never fails to be a 

 success. There is a small brown snout beetle, however, that works 

 into the side of the buds occasionally, as it does into those of other 

 roses, and these need to be picked each day until they have been 

 thinned out. It is seldom we have much trouble from this in- 

 sect, but this year it is more abundant than usual. 



The Tartarian maple is a small tree that should be better known. 

 It is perfectly hardy and makes a pretty, small tree when grown 

 in this form, or it does well in bush form. Its flowers are quite 

 conspicuous and appear after the leaves are nearly full size. Later 

 these are followed by reddish fruit, which is as conspicuous as the 

 fruit of the common red maple. The form commonly known as 

 Acer ginnala has rather prettier leaves, but is not quite so vigorous 

 in growth. 



About twelve years agO' we obtained from Arnold Arboretum 

 a high bush cranberry marked "Viburnum from the mountains of 

 Pekin." This is quite different from our ordinary high bush cran- 

 berry, and yet is plainly closely related to it, probably close enough 

 to have the same specific name. It is conspicuous when in flower 

 and in fruit and perfectly hardy. I think this is a shrub that is 

 worth introducing into cultivation. 



The Ginko', or Maiden Hair tree, we have tried repeatedly at 

 the Experiment Station but have failed to make a success of it. At 

 the old Grimes' place in Minneapolis I recently saw a specimen 

 of this tree that is fully eight inches in diameter and perhaps twenty- 

 five feet high, and as thrifty and perfect as an oak would be. I 

 am anxious to get hold of some of this stock and think we will 

 have to try it by grafting. The stock of this plant that we have 

 experimented with most largely came from seed obtained from the 

 U. S. Department of Agriculture and was grown, I believe, on 

 trees on the grounds of the department in Washington, D. C. It 

 seems from the tree at the Grimes' place, which is not especially 

 protected, that if we could get hold of the hardiest form of this 

 tree it would undoubtedly be of value for this section. 



Syringa villosa is now in its glory, and yet the common lilacs 

 have been gone over two weeks. When the common lilacs were 

 in flower I thought the Rouen, or Rothmagensis, lilac the most 

 beautiful of all that. I had seen. This is an old favorite and is some- 

 times called the Persian lilac, but has broader leaves and is much 

 hardier than the old Persian form.
