than meadow-fescue. From the table it is seen that the 
cost of some varieties of seed, such as tall fescue and 
tall oat-grass, is so high as to be well-nigh prohibitive. 
This difference in cost undoubtedly has much to do 
with the lack of popularity of many grasses, even in 
sections where they are superior to others. 
WEIGHT PER BUSHEL 
In most trade centres the sale of seed by the meas- 
ured bushel has been abandoned, and the much more 
satisfa¢tory method of selling by the hundred pounds 
substituted. However, the weight per bushel is highly 
important’as an approximate indication of quality, 
as it determines very closely the amount of chaff, 
although giving no information regarding weed seeds 
and adulterants. The recognized weights for the 
heavier grass-seeds, such as timothy and millet, repre- 
sent a good grade, while with the lighter seeds, such 
as blue-grass, orchard-grass, and redtop, the weight 
per bushel of good seed is considerably heavier than 
that commonly used. In most States the legal weight 
of Kentucky blue-grass is 14 lbs., but well-cleaned 
seed of good quality weighs from 24 to 28 lbs. Or- 
chard-grass, which is usually considered as 14 lbs., 
should weigh from 16 to 18 lbs. While chaff redtop 
often weighs 8 lbs. or less, good, solid, recleaned 
seed weighs 4o Ibs. One of the best safeguards in 
buying the lighter grass-seeds is to have the dealer 
determine the weight per bushel, which should, in all 
cases, come up to the weight shown in the following 
table ;
