PROFESSOR JAMES FURMAN KEMP
Introduction.—The state of New York is shaped like a shoe, with its toe pointing due west and a long spur extending from the heel to the east. In the upper part of the shoe where the ankle of the wearer would be placed, is the Adirondack region, containing 10,000 square miles of very sparsely inhabited mountain, plateau and forest.

CHARLES A. WHITE
WITHIN the past few years an increasing interest has been manifested in the black locust tree, Robinia pseudacacia. Many persons have begun to propagate it, not only as a wayside tree, but as a forest product; and issues of the public press lately have contained many articles and paragraphs pointing out the excellent qualities of the wood and recommending its general cultivation for economic uses.

A CONTRIBUTION TO THE THEORY OF SCIENCE

PROFESSOR WILHELM OSTWALD
ONE of the few points on which the philosophy of to-day is agreed consists in the realization that the only thing that is absolutely certain and beyond doubt for every one is the content of his own consciousness; or rather not so much the content of consciousness in general as merely the content of any given moment.

THE JEWSHARP

DR. H. CARRINGTON BOLTON
THE common English name of this primitive musical instrument is misleading, for it is not a harp nor has it any associations with Hebrews, as its appellation seems to imply. That it has nothing to do with Jews as respects either its origin or its employment is easier to demonstrate than it is to determine the real significance of its name, or the occasion of its invention.

DR. E. H. SELLARDS
NO insects are more abundant as fossils, and none so widely distributed through the various formations, as are the cockroaches. Their delight in moist places, often near the banks of streams, their firmly chitinized wings and body render them of insects among the best adapted for preservation.

HOW ROOTING AQUATIC PLANTS INFLUENCE THE NUTRITION OF THE FOOD FISHES OF OUR GREAT LAKES

PROFESSOR RAYMOND H. POND
A THOROUGH investigation of the biology of our great lakes is in itself a desideratum worthy the expense. From the purely economic standpoint, however, our Bureau of Fisheries has long recognized the necessity of knowing more of those conditions under which products worth millions annually are produced.

FRANK T. CARLTON
AT the beginning of the twentieth century, approximately one third of the total population of the United States were living in cities, and were classed as urban inhabitants. A considerable percentage of this twenty-five million human beings are to-day living in crowded and uncomfortable quarters, despite the evident fact that there exist in nearly all sections of the nation many valuable abandoned farms and half-deserted villages.

THAT the game of football as played at our schools and colleges is in ill repute with the people as a class, no one who keeps at all abreast of the times can deny. Nor can it be denied that there are many good reasons for the feelings of general disapproval.

SUBMARINE NAVIGATION

SIR WILLIAM H. WHITE
SUBMARINE navigation has engaged the attention of inventors and attracted general interest for a very long period. Its practical application to purposes of war was made about 130 years ago. The main object of that application was to threaten, or if possible destroy, an enemy’s battleships engaged in blockade by means of under-water attacks, delivered by vessels of small dimensions and cost, which could dive and navigate when submerged.

PROFESSOR W. B. PILLSBURY
SINCE Darwin wrote there have been many general formulæ advanced under which all forms of development might be brought, and while each has sufficed for a time, each has been seen to fail and each has been replaced with greater or less completeness when tested by a new set of facts.

OUR economic system rests on the free exchange of services. A state of society may some day be reached in which each will aim to give as much as he can and to take as little, but at present it appeals to our sense of fairness that each should ask for his services what someone else is willing to pay.
