32 CULTURE OF THE SWEET PEA 



One method recommended is to hollow 

 out a broad trench, twenty-four to thirty 

 inches wide and two inches deep, and then 

 sow the seed one inch deep in single or 

 double rows. The trench should be kept 

 open for six weeks in order to retain the 

 water. This system is very good in a gar- 

 den where all cultivation is given by hand; 

 but where many rows are grown and cul- 

 tivation is done with a horse and culti- 

 vator, it is manifestly impossible to make 

 or to maintain such a trench. Further- 

 more, when horse cultivation is used there 

 is difficulty in keeping the young plants, 

 if planted below the surface, from being 

 covered during the early cultivations. 

 Therefore, planting on the level is neces- 

 sary in field culture. It is advisable, how- 

 ever, in garden culture, to plant so that 

 when covered the row will be two inches 

 below the ordinary level.
