SHELTEK. 19 



tempts were made to check this evil by opening 

 trenches and cutting off the roots; but the 

 check proved to be only temporary. If large 

 trees surround the vineyard closely, ventilation 

 is materially interfered with. There are other 

 evils which we can not allude to here. The 

 distance at which clumps and sheltering belts 

 should be placed may be determined by the 

 kind of trees and the distances at which they 

 are planted apart. The proper distance for 

 belts and clumps is about fifty feet from the 

 vines. A hedge proper of Norway spruce, 

 planted for a height of ten to fifteen feet, may 

 be placed as near as twenty-five feet ; but forty 

 would be better, with the height of the hedge 

 increased to twenty feet. 



We must not be understood as saying that 

 shelter is indispensable to all localities ; we 

 know of vineyards that yearly produce the best 

 results that have no shelter ; but, notwithstand- 

 ing this, there are many places which, owing to 

 their geographical position, are liable to sudden 

 changes and violent winds ; and for all such, 

 protection of some kind is a matter of great 

 importance.
