DEPARTMENT REPORTS. 107 



der specimen with delicate drooping branches is [)hiced a few rods east of the 

 south end of the College Hall, where it is iu marked contrast with two others 

 of much stouter form. These were selected and planted by W. \V. Ti-acy, a 

 former professor at the College. One of the finest of the large specimens on 

 the grounds is northeast of Professor Deal's house near the posts in the foot 

 path. This tree is conspicuous for its symmetry and well developed lower 

 branches. 



SPRUCK, ORIENTAL— yl&ies oricnCatis. 



This tree seems to be as hardy as a Norway spruce, which it somewhat re- 

 sembles. The leaves are shorter than those of that species. 'LMie whole aspect 

 is much like that of a refined, slow-growing Norway spruce. It is not as com- 

 mon in cultivation as it deserves to bo, especially in our trying climate where 

 we are compelled to discard so many trees which are choice for ornamental 

 purposes in milder winters than we are certain of iu central Michigan. A sin- 

 gle specimen grows a few feet northwest of College hall where it was planted 

 by Dr. Thurber, a former professor at the College. 



SPRUCI5, WHITE— ^6ies alba. 



This is a small evergreen tree with compact growth of regular conical out- 

 line. The leaves are glaucous green in color, often a[)proaching to a bluish 

 tint, although the leaves and branches on close inspection appear a little stiff, 

 this is not so apparent at a little distance. It is a slower grower and more com- 

 pact in form than the Norway spruce. On account of the light color, it forms 

 a good contrast with the dark foliage of the Norway spruce. The branches of 

 old trees will become thin and bare unless cut back or kept growing on good 

 land. It grows in the nortliern States, sparingly in northern Michigan. The 

 leaves are longer, of a lighter color, the cones larger and the tree a more rapid 

 grower, and altogether it is a more beautiful tree than the black spruce. 



There are several other species of spruces growing in the nursery at the 

 College.

SOUR-GUM TREE. 



SUGAR-BERRY. 



SUMACH, POISON- iSAws venenata. 



This beautiful shrub grows in our swamps. It is one of the plants of our 

 State which is poisonous to the touch. I am glad to say we have no specimens 

 about the College grounds, although there may still be a few specimens in the 

 swamps on the back part of the farm. I will cidd that a specimen has been 

 planted and labelled on a small island in the pond of the wild garden. 



SUMACH, STAGHORN— ie/ms Ujphlna. 



This large shrub is distinguished for the brilliant red color of its primate 

 leaves and its red fruit in autumn. It suckers badly on soft ground. A 

 specimen grows a few rods southwest of the Secretary's house ; also on the 

 river bank near the west entrance to the grounds. 



SWEET-GUM TREE.
