ferred. What is here said of the superiority of the White Spruce 

 over the Norway is also true of the Black Spruce, (Picea mar- 

 iana (Mill) B. S. P.) a native of this country much like the 

 White Spruce in manner of growth, but differing- in color and 

 in some minor botanical characters. Both of these spruces have 

 a number of horticultural varieties most of which are well 

 worthy of trial as ornamentals. 



Arborvitae* (Thuja occidental} s L.) The behavior of the 

 trees of this species has been very satisfactory, indeed. All 

 have made a steady, rapid growth and their average height is now 

 15 feet and 'their circumference, 14 inches. Three of the largest 

 specimens were transplanted without much trouble from the 

 Station grounds to the College campus last winter, and seem to 

 have suffered but little from the change; trees of this age could 

 hardly have been moved successfully without so planning that a 

 large ball of earth, weighing in this case more than a ton, and 

 frozen solid, could incompass and so retain the entire root 

 system. Smaller trees in the new plantation have been moved 

 without the loss of a twig. 



This is a common ornamental in most parts of the country. 

 Frequently we hear it called Cedar or Juniper. There are a 

 great many varieties of this species offered by nurserymen some 

 of which are to be preferred to the tree in question; this is nota- 

 bly true of the Siberian Arbor vitae, a variety with foliage much 

 superior to that of the common tree, which is hardly ever to be 

 seen without a mixture of yellow leaves interspersed with its 

 green foliage, and which in the winter turns a brownish color 

 as if seared bad qualities not found in the variety named. 

 For particular purposes other varieties have much merit. 

 Nearly all of the Arborvitaes make fine hedges as they stand 

 trimming remarkably well. Some of these trees should find a 

 place on the -premises of all who are planting for ornament.
