After reading your article in May number of the Gardeners' Monthly, I am inclined to say that I have never seen a head of red clover without seed since 1838, either first or second crop, and that the heaviest crop of seed and the largest and fullest head ever grown on the status of a crop of winter wheat sown the same spring - the land occupied by me - was saturated by plaster of paris from the overflow of a sulphur spring, so that for twenty yearly sowings I never cut a crop of wheat. After draining the land and cutting off the water have made on same land from 20 to 30 bushels of extra wheat. I am convinced that the loss of twenty years' crops was caused by the plaster of paris.
The humble-bee theory does not go down with me, as we have almost none. Sandusky, O.
[Undoubtedly in situations where the conditions are favorable to reproduction, and vegetative exuberance is held in due check, the first crop of clover will seed as well as the second. - Ed. G. M].
