Distances. Under glass sow in drills a few inches 

 apart, prick out at the second leaves to four inches

 open, seed-bed drills six inches or more apart. Sown 

 where the plants are to stand, drills should be one 

 foot apart. 



Depth. Under glass one-fourth inch. In the open 

 one-half to one inch, ac-

 and successively every ten 

 days or two weeks there-

 thinnings transplanted
