Cultivation. — " Frequent cultivation " 

 should be a motto in growing a vineyard. 

 The surface should be kept mellow by 

 the frequent passage of the cultivator or 

 grape hoe. This latter, is an exceedingly 

 useful implement in the vineyard or 

 small fruit plantation. In a dry season 

 the importance of frequent shallow 

 cultivation, as a means of retaining the 

 moisture of the soil, is not easily over 

 estimated. A good practice is to plough 

 to the vines in the late summer and 

 away from them in the spring. The fur- 

 rows nearest the trellis should be very 

 shallow, as the surface soil is filled with 

 fibrous roots. The cultivator and grape 

 hoe will do the work during the remain- 

 der of the season. A cover crop is of 

 great service in the north, to catch the 

 snow, and thus afford protection to the
