important fact; from them it is more than likely that the

sible more hairy, in having the stem and branches darker co-

The colour of the seeds is the only specific mark, if so trif-

This is less cultivated than Moog, the grain being some- 
what less esteemed, and of less value, the same soil suits it, 
and itis frequently mixed and sown with other sorts of grain, 
viz, Holeus saccharatus,and Holcus sorgum, Linn, These cul-

it occupies the surface of the ground, keeping it cooler and 
moister than it would be without it. It is sown earlier than 
the green pessaloo, generally just before the close of the 
rains, because it likes moisture more than the other, requires
