The ground mole has been for a long time a constant source of annoyance to gardeners and farmers, and the question has often been asked, " Is there no way of getting rid of this pest without the tedious process of trapping it?" which at best is only a partial relief. To this question I answer, Yes. The remedy I have known for many years, and I wish to give the public the benefit of it through the columns of the Gardeners' Monthly. Like everything else that is given gratis, perhaps some will be found to deny or contradict the good effect of this remedy, but I challenge contradiction and demand a fair test from the public. One pint of the seed of the castor oil bean (Ricinus communis, or Palma Christi) is sufficient to clear any garden of an acre or less for the season, if properly dropped in their runs, which is simply to thrust the forefinger into the mole hill and then drop a bean there, which he will be sure to eat next time he comes along; at the same time covering up the hole made by the finger with a bit of earth, chip, stone, or clod, so as to make the run tight as before and keep out the light. This plan I have found effectual in all gardens where I have tried it. It is not quite so satisfactory in grass lands, because it is often hard to find all their runs in the grass.
Also, in planting corn in fields where this pest abounds, if a seed be dropped occasionally in the hill along with the corn the mole will eat the bean in preference to the corn, and as sure as he eats it that is the last of him. If this plan be adopted when the moles first begin to run, which is generally after the garden is made and nicely planted, they are easily got rid of, and no trap of any kind need ever be introduced into the garden. This saves much time, labor and annoyance.
