formation of a dense population. In the lower part of this favoured region the banana grows. This plant requires scarcely any labour in its cultivation; and, according to the most moderate estimate, taking an acre of wheat against an acre of bananas, the bananas will support twenty times as many people as the wheat. Though it is a fruit of sweet, rather luscious taste, and only acceptable to us Europeans as one small item of our complicated diet, the Indians who have been brought up in the districts where it flourishes can live almost entirely upon it, just as the inhabitants of North Africa live upon dates.
In the upper portion of this district, where the banana no longer flourishes, nutritious plants produce an immense yield with easy cultivation. The yucca which produces cassava, rice, the sweet potato, yams, all flourish here, and maize produces 200 to 300 fold. According to the accepted theory among political economists, where the soil produces with slight labour an abundant nutriment for man, there we ought to find a teeming population, unless other counteracting causes are to be found.
The history of the country, as far as we can get at it, indicates
