"Bread-eaters have almost eaten up the reserves of wheat, and the 1897 harvest being under average, the conditions become serious. . . . It is clear we are confronted with a colossal problem that must tax the wits of the wisest. Up to recent years the growth of wheat has kept pace with demands. As wheat-eaters increased, the acreage under wheat expanded. We forget that the wheat-growing area is of strictly limited extent, and that a few million acres regularly absorbed soon amount to a formidable number. The present position being so gloomy, let us consider future prospects."
He then deals successively with the United States, Russia, Canada, and other countries. In regard to the United States he remarks:
"Practically there remains no uncultivated prairie land in the United States suitable for wheat-growing. The virgin land has been rapidly absorbed, until at present there is no land left for wheat without reducing the area for maize, hay, and other necessary crops. It is almost certain that within a generation the ever-increasing population of the United States will consume all the wheat grown within its borders, and will be driven to import, and, like ourselves, will scramble for a lion's share of the wheat crop of the world."
It is difficult for a citizen of the United States who has given any attention to the potential of our land to conceive of such views being held by an Englishman of highest scientific intelligence. When I was in England last summer I had a long interview with the editor of one of the papers of widest influence in all Great Britain. I then remarked that there were forces in action in the United States in three or four different directions which would profoundly change all the conditions of British industry, and render the English-speaking people of the United Kingdom and the United States more and more interdependent. It is seldom that one finds more than an occasional half a column in any great English paper devoted to the subject of our economic relations and to the development either of the American iron industry, of its agriculture, or of the cotton production and manufacture. Yet, in all these branches of industry, profound changes of world-wide importance, and yet of greater importance to the people of Great Britain, are now in progress. I may venture to say that this address of Sir William Crookes marks even a more profound ignorance of the forces in action in this country than even I had ever comprehended. Sir William Crookes next submits the following computation:
"The rate of consumption for seed and food by the whole world of bread-eaters was 4.15 bushels per unit per annum for the eight
