I STAIGREEN LAWN SEED | 
I April is the best month during the Spring to make your lawn. "While the proper preparation of the | 
1 ground, fertilizing, rolling and watering is considered very essential, the mixture of grasses is a very a 
I important one and should be given considerable thought. | 
I 25-Pound versus 14-Pound LAWN SEED | 
I Many low-price Grass Seed mixtures weigh only 14 pounds per bushel. This indicates either a good | 
I proportion of chaflf or some of the real good varieties in the rough state, not properly cleansed so as to | 
I leave only the vital part and less of the chafT or shell. | 
i In other words, so many less seeds to the quart or pound that will germinate and grow real grass. 1 
I Why Not Buy the Re-cleaned Kind? | 
I A mixture of grasses weighing 25 pounds per bushel, of high germination and purity, permanent in 1 
1 nature, the varieties carefully proportioned so that they will succeed one another in brightness of f 
I foliage, with the result that the lawn, even in its first year, will have a bright, rich green color from | 
1 early spring until covered by snow. 1
