This paper was received in its proper season from Mr. Csesar, but it being in the holiday season I could hardly find time then to give it its proper attention. The roots spoken of in his note I forward to you this day by mail. We have no one with us who can give any information respecting it. Any information you may be able to give respecting it, will be duly appreciated by the many horticulturists in this vicinity.

Hazelwood, Dec. 13th, 1879.

Dear Sir: - A week ago I received from a friend on Staten Island a package of young plants of Raspberry, of stocks which had given a very fine crop this year. When I began to plant, I observed at once very remarkable excrescences on the roots, as well on the small ones as on the main roots. In cutting them off and examining them with a sharp knife, I found small white worms in several of these excrescences, worms about one-eighth to one-quarter of an inch long, thin, and undoubtedly an insect by the sting of which this disease of the roots was produced. I have never heard of such kind of disease, and the chief book, which I always consult in any matter of orchards, etc., the book of A. J. Downiug, makes no mention of any disease of Raspberry. Of course I cut off, when I planted, the least vestige of the disease, but would feel obliged to hear some experienced orchardist's information on the matter. I accompany this with some such roots affected by the disease.

I am, yours respectfully,

Henry L. Cjssar.

[There are a number of insects that infest the roots of the Raspberry and Blackberry, their attacks usually resulting in galls of more or less size. The particular one which forms these very large ones, would probably very much interest the entomologist. To the horticulturist we fear no other course can be suggested than to be careful in planting, that he has plants with roots wholly free from these galls, and if he has a plantation badly infested, to dig up and burn the plants, and set out plants on wholly new ground. Some varieties will be found greater favorites with some insects than others, for generally they have nice tastes. When one has a large plantation, it becomes a serious matter to know best how to deal with them. The best advice we can give, is the preventative one, - never plant without examining the roots, so as to avoid introducing an enemy. - Ed. G. M].
