"Subscriber," Baltimore, Md., writes: "I enclose sample of grass which comes up on all very sunny and exposed places on the lawn from July till killed by frost in the fall. Please answer in the Monthly the cause".

[In this part of the world this is known as " Fall Grass." It has probably other names in other localities. Botanically it is Panicum sanguinale. It is one of the greatest enemies to a good lawn, as it destroys every kind of vegetation, taking the ground wholly to itself. This would be no consequence, rather an advantage, if it were perennial; but, being an annual, there is a bare place in the spring, and no grass until mid-summer. The only way to get rid of it is to prevent it from seeding; but this is by no means easy, as the seeds are often produced down in among the leaves where they can scarcely be seen. It flourishes best where the soil is damp and rich. In dry soils the Fescue and Blue grasses will hold their own and stubbornly refuse to be crowded out. It may help some to sow these grasses on the bare spots left by the Fall grass in the spring. - Ed. G. M].
