Under our eye for some years has been a lawn on which at least half the space was covered by the unwelcome fall grass - Paspalum sanguinale. By the advice of the writer, attention was given to encouraging the growth of the evergreen grasses, chiefly the "blue grass," Poa pratensis. The lawn had an occasional top dressing of guano, or of other fertilizers that had no seeds of weeds in them, and the lawn mower was never allowed to cut nearer then half an inch of the ground. It is interesting to note how nearly the enemy has been crowded out. This season patches a few feet over only remain to it, and this though no blue grass seed was sown among the fall grass as recommended.
