Having been a diligent reader of the Horticulturist from its commencement (if not in point of time at least so far as the volumes themselves are concerned), I have watched with much interest the warfare carried on with the curculio, and the various devices contrived to kill the little Turk or drive him from his prey. As yet I believe we are without a sure and simple remedy; but the following facts have been gathered from the records of past successes and defeats. The inference is my own.

1. No certain remedy has yet been found - one which will protect all the trees in an orchard or locality.

2. Some trees have been preserved and been loaded with fruit, while the crop upon others standing near them has been totally destroyed.

3. In such cases the preserved trees have generally been distinguished from the others by the application or vicinity of lime, sulphur, plaster, pigs, fowls, calves, manure, water, or some other agency offensive to the curculio.

4. The application of all these remedies often fails, and, where applied to a whole orchard or neighborhood, rarely does any good.

5. The curculio deposits several eggs in one fruit and one incision, and if fruit be scarce will make several incisions in the same fruit.

Connecting these facts together, it seems to me that the great secret of the success of comparative experiments with such remedies as lime, sulphur, plaster, etc, lies in the fact that the curculio prefers clean fruit and conditions favorable to the rearing of its progency to the contrary; but it will try to rear them, let the conditions be what they may. If, then, we have an orchard of plums let us always leave a few of the poorest trees for the curculio and take our revenge on him after he has done his work by picking up and destroying the fruit and eggs. In a city it generally happens that some near neighbor is lazy enough to leave his crop in such a state as to protect ours; but if isolated, let us take care that we do not render all our fruit equally disgusting to our tormentor, for then he will assuredly levy his con-tcibutions from all trees alike.

But the curculio no doubt prefers clean fruit and a favorable location for propagating its species, and if we offer it these conditions it will rather make a second puncture in such fruit than go to that which is covered with lime, and under which chickens or pigs stand with open mouth to receive it.
