I read Charles Black's notes on the "Strawberry Blight," in the January number of your invaluable journal with intense interest, for if the blight continues spreading and no remedy is found it will soon play havoc with the strawberry crop. Although it never occurred to me that the louse caused the blight until reading Mr. B.'s theory, yet so far as my observations go, I too have always found the louse in greater or less numbers on the roots of plants effected with the blight. The remedy for the destruction of the louse is simply a good dressing of un-leached wood ashes; early in the Spring, wood ashes as is well known is a superior fertilizer for the strawberry, and from experience I have found it a dead shot to the louse. It must be remembered that the ashes are to be unleached however - leached ashes have but little effect comparatively. Now, if Mr. Black's theory be correct, we have at once a remedy for the blight and can have plenty of strawberries by the application of ashes after the manner that Darwin produced clover seed by increasing the number of cats.
