FORESTRY IN SWITZERLAND.

author adds that he has himself had avenues of ornamental trees set out on 

 slopes already somewhat gullied, and found that after a subsequent adequate 

 spread of root they grew thriftily. 



Concerning declivities in process of being carried away by the trickling 

 of springs beneath them, the author remarks that no staking or planting 

 could, of course, avail so long as the flow of water is not entirely cut off or 

 completely brought under control and led gff elsewhere. In the first place, 

 the interior of the hill and its substrata must be looked after, i. e., drained 

 off, and not until then can its exterior surface, if still required, be rendered 

 firm by a growth of trees of moderate height. 



In the table on pages 238 and 239 the author gives alphabetically, under 

 their latin names, the trees and bushes most available for the object stated. 



In concluding his essay the author calls attention to the sodding of the 

 ground as an important factor for rendering it compact and covering it, as 

 well as in protecting the seeds and tender plants on sunny exposures. The 

 importance attached in other countries to this protective measure is shown 

 by the pains taken to transport sods from the low grounds to wild and ele- 

 vated barren slopes to protect plants from the north wind, and also by the 

 strewing of grass-seed, which is capable, within a short time, of forming, 

 even in the roughest soil, an impenetrable network. For sodding in high 

 land, esparcet, mixed with bibernelles, feed-grass, tare, meadow-oats, Spanish 

 clover, &c. 



DEALERS IN SEEDS AND PLANTS. 



Where so active an interest is officially shown in all that pertains to the 

 growth of trees and plants it is but natural that a correspondingly active 

 commercial interest should exist. There are in this city a number of enter- 

 prising dealers in this line of products whose names and addresses I give 

 herewith :
