An excursion on the 28th to Cahokia Mound in Illinois, five miles out on the

O. & M. Railroad, yielded the following species:

Boltonia glastifolia, Polygonum ramosissimum, Montelia tamariscina, Leptochloa fascicularis, Herpestis rotundifolia, Oxybaphus nyctagineus, Chrysopsis villosa and Iva ciliata.

The country was mostly cultivated, and the fields not recently plowed were densely grown up to tall ragweed, (Ambrosia trifida.) which obscured the view even from the mounds.

It will be observed that these are all spring flowers." They bloomed reguand then, during the hot months of July larly from April to June, went to seed, and August, lay as dormant as in midwinter. The herbaceous species, Viola, Fragaria and Houstonia, withered away almost entirely, and the flowers borne in autumn were on new plants that came out of the ground in September. In the shrubly forms the flowers were found on new green shoots which had started afresh after the cooler and more moist weather had set in.

Could the September and early October weather continue a little longer many of these plants would yield two crops of fruit each year.

Field and Forest

A MONTHLY JOURNAL

DEVOTED TO THE NATURAL SCIENCES.

CHARLES R. DODGE, EDITOR.

BULLETIN OF POTOMAC-SIDE NATURALISTS' club.

WASHINGTON:
THE COLUMBIA PRESS.

FIELD AND FOREST is a monthly publication devoted to the Natural Sciences, and is also the Bulletin of the Potomac-side Naturalists' Club of the District of Columbia.

The subscription price for the United States and Canada, payable in advance, is ONE DOLLAR. Foreign subscriptions, $1.25, or its equivalent. Single numbers furnished

at 10 cents a copy, or twelve for $1.

Contributions upon subjects pertaining to Natural History, are solicited from all. Address all communications Editor FIELD AND FOREST,

P. O. Box 273, Washington, D. C.

For some time past there has been a need for a medium through which students of Natural History and the kindred sciences could communicate with each other the re sults of CURRENT OBSERVATION in the field and laboratory, and, at the same time, place on record notes of any new facts of general interest to the scientific world that might come under their notice, as it is believed that many valuable facts bearing upon the Natural History of our land are lost to science, because not deemed of sufficient importance for publication in our larger magazines.

To meet this want, at the Nation's Capital, FIELD AND FOREST was projected, and in June 1875, the initial number was published. The limited number of its pages however, proved a serious drawback to full success, and so it has been thought advisable, with the opening of the second volume to double the number of its pages, and to enlarge its scope and FIELD of usefulness.

Still under the patronage of the Potomac-side Naturalists' Club-a natural history society founded twenty years ago—with a corps of Contributors composed mainly of gentlemen of recognized authority in the various branches of science, many of whom are eminent in their specialties, its tone and standing need not be questioned. '

It is not intended, however, that it shall be exclusively the bulletin of any society, or the record of any particular locality, but that it shall be devoted to the fields and forests of our whole country. We shall aim to make it popular by giving fresh and interesting articles on various topics, notes relative to the birds, animals, fish, insects, plants, &c., of our American fauna and flora, as well as carefully selected extracts from the foreign scientific publications.

A monthly record of the proceedings of the Naturalists' Club will be given, and ab stracts of papers read before the club will be published when upon subjects of special interest.

In short, our aim is that FIELD AND FOREST shall occupy a middle ground in scientific literature, by making it a journal of information for the student and observer, as well as a repository for notes and observations, that might otherwise remain hidden between the covers of an unpublished journal or note book. To that end we invite brief contributions from ALL students of nature upon topics of general scientific interest, as field notes, brief accounts of experiments or investigations, and information in regard to Societies, as well as communications upon subjects more technical.

We think the field is new, and can be made a useful one, and that our little journalwith the hearty co-operation of all who are interested in the objects for which it was esablished-may prove a complete success.
