FOREST TREES AND SHRUBS. 91 



6S. Engleman Spruce (Abies Englemanii.) Have found it only 

 on the Niobrara and tributaries. 



69. Douglass Spruce {Abies Douglassii.) On the Niobrara and 

 its tributaries. 



70. White Cedar (Cupressus thyoides.) Northeast Nebraska, 

 along: the Missouri and on the Niobrara. 



71. Red Cedar (Juniperus Virginiana.) Generally scattered 

 over the State where timber occupies bluff lands or dry bottoms, 

 but abundant only in a few localities in northeast Nebraska, on the 

 Niobrara, and on the Loup. Extensive groves occur on the Loups 

 and their tributaries, and on the Niobrara and its tributaries. It is 

 one of the most hardy and most easy to cultivate of all our ever- 

 greens. A slow grower, it is still a most desirable tree, because 

 of its great hardiness, and when trimmed into shape, of great 

 beauty. 



After subtracting- from the foregoing list ten kinds that are as 

 frequently shrubs as trees, the number of species and varieties 

 that are left is still sixty-one. In the St. John's timber, in Dakota 

 County, and at the edge of the bluffs, I once on the space of two 

 acres counted eighteen sjuecies of the trees included in this list. 

 Facts like these demonstrate the great adaptation of Nebraska to 

 the growth of forests. A little assistance from man, and nature 

 will again gradually clothe a large part of the plains with a cover- 

 ing of timber. 



Shrubs. 



1. Papaw (Asimina triloba?) Southeastern Nebraska. Some- 

 times becomes a small tree. 



2. Creeping Barberry (Berberis repens.) On Loup and Nio- 

 brara. One foot high in the mountains; here from one to two feet 

 high. 



3. Downy Hudsonia (Hudsonia tomentosa.) In counties border- 

 ing the Missouri, and occasionally in Johnson, Lancaster and 

 Saunders. Everywhere rather rare. 



4. Shrubby St. John's Wort (Hypericum proiificum.) Have 

 seen it only on south side of the Nemaha in Richardson County. 



5. Naked Clustered St. John's Wort (H. nudiflarum.) Widely 

 spread over eastern Nebraska, but nowhere abundant. Have seen 

 it on the Republican, on Wood River and the Elkhorn. 



6. Prickley Ash (Zanthaxylum j&mericanum ) Along the Mis- 

 souri, Niobrara, Blue, Republican, etc.
