not permit him to pay any higher wages, and the poverty of the planter prevents him from making the outlay necessary for the proper cultivation of his land.'

"Few coffee planters have anywhere near a reasonable amount of their land under cultivation for the reason that with the poor help and methods now existent they are unable to extend their plant. The regular labor, employed all the year round, the peons—who form a relatively small percentage of the entire number available for work—are paid for a full day's work, and their degree of anemia is such as to prevent their doing but about 50 per cent of what they are paid for doing. Our estimate of the relative efficiency of labor was made from what the planter himself told us and by a simple experiment which we tried upon about 500 adult workers in different parts of the interior. We questioned each one as to the amount of coffee he could pick in a day and found that from two to three almudes was the utmost the majority could do, and that one almud was too much for many. Some stated that after picking a sack full in a remote part of the plantation they were unable to get it in to the mill without a mule, on account of the fact that their limbs refused to bear them up. When these people were working at light work, and at a time when the more they picked, the greater the profit to themselves, is it reasonable to suppose that when working for a wage without this incentive this 50 or 60 per cent labor would be any more efficient? This reduction in laboring capacity demonstrates what a heavy toll is paid by both employer and employee to uncinariasis in Porto Rico.

"As to absentee landlords, Weyl says:

'Many of the absentee owners of Porto Rican properties and many of their agents in Porto Rico consider the island and its population as equally fit for the crassest exploitation, and are as contemptuous of the people as they are enthusiastic about the island. The current use by many Americans of an opprobrious epithet for Porto Ricans bespeaks an attitude which takes no account of the human phase of the problem, but considers the population as composed merely of so many laborers willing to work for such and such a price.'

"Thus the poor laborer, his earning capacity cut down by his disease, with employment which is at best very irregular, with his sick wife and children for whom he has to buy 'iron tonics' that cost all that he can rake and scrape together, without money for clothes, much less for shoes, with a palm-bark hut not too well protected against the damp cold of the grove in which he lives, with not a scrap of furniture save, perhaps, a hammock, and, worst of all, with a miserable diet lacking in proteids and fats, lives from day to day, saving nothing, knowing nothing of the world beyond his plantation, working mechanically simply because he is not the drone he has been too frequently painted outside of Porto Rico, but without any object save to keep on living as generations have done before him. It has been our experience that when he is asked 'Why have you sought our dispensary?' the answer has almost invariably been, 'Because I can no longer work.' The jíbaro, nevertheless, has ever been the lever which has raised the bank account of Porto Rico, and with an average of 40 per cent of hemoglobin and two and a half millions of red corpuscles per cubic millimeter he has labored from sun to sun in the coffee plantation of the mountains, in the sugar estate of the coast land, and in the tobacco field of the foothills, in addition to his personal coöperation in other industries and commercial enterprises. He is a sick man and deserves our highest respect, and merits our most careful attention as a vital element in the economic life of the island. The American people should take seriously into account his future, which is at present anything but promising."

OVERPOPULATION

When we say that a country is overpopulated we speak in relative terms, inasmuch as the overpopulation of a country does not depend upon the density of the population alone, but also upon the ability of that country to produce a sufficient amount of foodstuffs to maintain its population. Thus a country which has a relatively small population and a still smaller ability to produce foodstuffs would be more overpopulated than a country of similar size with a larger population and a still greater production of foodstuffs.

In considering the case of Porto Rico, we find that the Island contains 8,317 square kilometers of land. The estimated population at the present time is 1,200,000. This gives about 140 persons to the square kilometer as compared with 72 persons in France, 237 persons in Belgium, and 252 in Saxony. If the productive ability of the soil of Porto Rico is as great as that of Belgium and Saxony, we must conclude that Porto Rico is not overpopulated. If for any reason it is less, then the extent of overpopulation increases directly as the soil grows less in productive ability.

Porto Rico has about ten times as many inhabitants per square acre as the average throughout the United States; but the conditions of climate do a great deal to equalize this difference. In the first place, the soil is available in Porto Rico for the production of crops throughout the twelve months of the year, whereas in parts of the United States and in northern Europe the soil is usable for only a portion of the year on account of its unproductive condition during the winter months. Another matter that must be taken into consideration in the question of overpopulation, is the severity of the climate. Where the climate is severe, the country will maintain in comfort a much smaller population than where the climate is as friendly to the human race as we find it in Porto Rico.

Of the population of Porto Rico in 1910, about 75 per cent lived in communities that had less than 500 inhabitants, showing conclusively that the great majority of the people of Porto Rico should be classified as rural inhabitants and that the problems which affect the rural people of Porto Rico are the problems which would affect, to a great extent, the entire Island. Only two cities in the Island have a population of more than 25,000, while only 30 would fall under the head of urban territory, that is, towns which have a population of 2,500 or more.

The rate of increase of population in Porto Rico is far in excess of the rate of increase in the United States, and this is one of the things that must be taken into consideration in considering the question of overpopulation. In the United States the rate of increase among the class of people whose salaries range from $700 to $2,500 is from ten to twelve per thousand. In Porto Rico, the rate of increase is about twenty per thousand.

The following table shows a comparison between the birth rate, death rate, and rate of increase in the United States and Porto Rico, the figures given representing the birth and death rate for every thousand of the population in each country.
