This variety, as found in the Black Hills, is being brought 

 into cultivation by western nurserymen. H. C. Warner, 

 Forestburg, S. D., reports: 



"THE SILVER CEDAR, (funiperus scopulorum}, is beauti- 

 ful when the leaves hold their color, but often they lose that 

 silver green and then are no better than the Red cedar.'' 



A. Norby, Madison, S. D., writes: "The Silver cedar is a 

 good tree worthy of planting." 



RED CEDARS FROM SEED. A number of inquiries have 

 been received at this Station from places along the Missouri 

 river and other rivers in the state asking for information as 

 to the raising of Red cedars from seed. The correspondents 

 state that they have gathered seed from native trees in the 

 vicinity but have failed in germinating them. This is be- 

 cause the waxy layer covering the seed effectually prevents 

 access of moisture. One way to remove this waxy layer is 

 to stratify the seed one year before planting. By this is 

 meant that the berries, as soon as gathered, are mixed with 

 sand in a small box such as crackers come in. This box 

 with holes in the bottom for drainage, is buried just beneath 

 the surface of the soil in a well drained spot with a mulch 

 over the soil to prevent drying out. The second spring fol- 

 lowing the seeds are planted. Some nurserymen have 

 learned the art of removing the wax or gum by rubbing 

 with wood ashes, sharp sand or lye the first fall and 

 planting the following spring. However, the method is not 

 recommended to amateurs. 



Arborvitse. 



Arborvitse. (Thuya occidentalis, Linn.). Native from 

 North Carolina to Nova Scotia west to Illinois and eastern 

 Minnesota, north to Lake Winnipeg. In this region it is 

 very common in swamps and wet soils. The name White 

 cedar is often applied to the Arborvitse but this properly be- 

 longs to another tree native far south.
