" Mrs. J. D. C," Upper Sandusky, O., writes: "I see nothing in your valuable monthly of which I have been for many years a careful reader, in relation to a very troublesome pest, seen this season for the first time in this section on chrysanthemums.

" It is black, looking much like a flea, or the pest that so often attacks young cottage plants. Will you or some of your contributors to the magazine, be good enough to let it be known if there is any way of destroying them without injuring the leaves and plant? They are alike thick in greenhouse and outside, and these late hard frosts leave them as lively as ever. Between dry weather and these pests, chrysanthemums are almost an entire failure this fall. A friend who has tried dusting with dry hellebore, says it makes the leaves curl".

[Hellebore powder, or any poisonous substances that kill insects that-feed on leaves, powdered on them, will not kill any of the Aphis family, because they do not eat, but suck the juices of the plants, the juices, of course, being beneath the poison. We have to reach insects of this class through their breathing pores. In a greenhouse or any closed place, tobacco smoke will do this; and in the open air, it is found that strong tobacco water will penetrate them sufficiently to kill them. A few strong syringings with tobacco water would be a complete remedy, we think. - Ed. G. M].
