tho crop from which tho selection WAS
made. Il is believed, however, that by
continued GROSS breeding and selection
Ia succeeding years tho quality Of tho
cotton may be improved without loss Of

along this limo has already been started
in Q small way by the department.
which it is hoped may be enlarged.
1t has boon shown that much osn bo

individuals, for in this way tho rosis.
