Messrs. J. B. Lippincott & Co., of Philadelphia, have arranged for the publication of a complete illustrated work on the insects injurious to horticulture and agriculture. It is to be prepared by Mr. Wm. Saunders, of London, Ontario. There has been an immense amount of useful information brought out about insects of late years, but it is scattered through such a vast number of publications tat no one knows where to look for it when needed. It is fortunate that the lot of preparing such a work has fallen on Mr. Saunders. While standing among the leaders in scientific entomology, he happens to be at the same time an enthusiastic horticulturist, and so knows just what we need in this line. In addition to this he is one of the leading chemists of America, and must have a practical acquaintance with insect destroying substances. It is rare that so many qualifications unite in one individual, and we may therefore look for a work of standard reference for all time.
