It is wonderful what an immense amount of intelligent information is distributed in catalogues now, over what was to be found in them a quarter of a century ago. This has particularly struck us in looking over the catalogue made by Mr. Grieves Secretary of the Greenbrook and Paterson nurseries of New Jersey. It is a complete dictionary of gardening as far as the plants of common cultivation are concerned. As a sample we take the following about a well known and curious plant:

"Sarracenia, named in honor of Dr. Sarrasin, a French physician. These are curious and interesting plants, known as the side saddle-fiower.. They inhabit the bogs of this country. The leaves of all kinds are singularly formed into pitchers, which are lined inside with hairs, whose functions are but imperfectly understood. They grow well in pots partly filled with rough peat soil and the rest sphagnum moss, in a moderately cool, moist atmosphere. Natives of North America".

Notes on the Aphidae of the United-States, by Chas. V.,Riley and J. Monell - Published by the Department of the Interior. In this valuable contribution Prof. Riley makes known for the first time that the eggs of some of the gall making pemphiginae, the section of aphi-dian insects to which the phylloxera is closely related, are deposited in the Fall in crevices of the bark, and not in the earth on the roots, and this may lead to intelligent study of modes of destruction. Of aphides and their close relation, the treatise is chiefly the work of Mr. Joseph Monell, a name new to science. Mr.. Monell is a young man of St. Louis, generously educated by Mr. Henry Shaw, whose numerous good works, in connection with St. Louis, is now almost world-wide, and who we are quite sure could wish no better return for his good work than the prospect of life long usefulness as exhibited by his young protege in so admirable a scientific treatise as this. It will be news to most of our readers that there are thirty-eight different species of aphis, including near allies-described in this treatise. No doubt most persons who have been troubled with these miserable plant lice ever stop to consider that their "brothers and sisters and cousins and aunts " in species made a huge list amongst themselves.

It must have taken a great deal of patience and judicial power over scattering facts to have worked' out the life histories of so many of, these minute insects; and Mr. Monell will need no better inducement to keep on with his very useful studies than the praise he will certainly receive from all, who interested in plant lice, profit by what he has already done.
