short-live.d plants included in the mixture will have disappeared 

 by the fourth season, and ultimately the whole of the area should 

 be occupied by permanent kinds. 



In making up mixtures, after deciding upon the species to be 

 included, it is usual to allot to each an aliquot part of the area 

 according to the amount we wish to have present. If, for example, 

 we wish to allow Meadow Fescue ten per cent, of the area, on 

 looking at Table II we find that 30 pounds of seed are required for

an acre, therefore 3 pounds will be necessary for one-tenth of this 

 area. These quantities in Table II are for absolutely pure and 

 germinating seed, that is, for seed having a "real value" of 100 per 

 cent. It is necessary to correct these weights according to the 

 " real value" of the seed being used. This is done by multiplying 

 the weight given in the table by 100 and dividing by the figure 

 giving the "real value" of the seed to be sown. If ya. the above 

 example the Meadow Fescue seed has a "real value" of 90 per cent.,
