 should always be tested before seeding. When drilled 

 close, no cultivation is given the plants, but when seeded 

 in rows, they should be cultivated frequently during the

 the leaves, which form the most valuable part of the hay, 

 will be lost, and the stems will become woody and unpal- 

 atable. On account of the ease with which the leaves 

 are broken off when dry, the curing should be done in the

 swath for a day or so, and the drying can then be com- 

 pleted with less loss of leaves by cocking. After a few
