A correspondent from San Barnardino says: " You advertise a Pyrethrum cinerariaefolium for a firm in Stockton. There is no such plant known in our California Botany, and I believe it is an arrant humbug."

[On looking again over the advertisements, we do not see that the advertisers claim that the plant they refer to is a native of California. Indeed they say that it is the Pyrethrum cinera-riaefolium, which every good botanist knows is a native of Dalmatia, and is the plant from which the celebrated Dalmatian insect powder is made, as Persian insect powder is made from Pyrethrum roseum. We do not know whether a person has a right to call what is well known as Dalmatian Powder by another name; that is, that Californian insect powder, ought fairly to be given to the Dalmatian powder plant; but as the fair botanical name is given, no charge of inten tional deception can be sustained; and after all it shows that the seed has been raised from plants grown in California, and not imported seed from Dalmatia. We may say, however, that we know nothing of the firm advertising, but there is nothing whatever on the face of it to warrant us in supposing it a "humbug." If they are not offering the true Pyrethrum that would be another matter, but we do not see why they may not have it true. If our correspondent can show this, we shall be glad to have the exact facts, for though not responsible for what appears in our advertising columns, the publisher will advertise nothing wrong if he knows it.

So far we have no reason to believe the advertisers are not dealing fairly. - Ed. G. M.]
