CHAP. XVI. _Why are some Countries found very populous in respect of others, equally well calculated for Improvement?_ This question comes immediately under the influence of the principles already laid down, and must be resolved in consequence of them. It is with a view to make the application of these, that I have proposed it; and, in the examination, we shall prove their justness, or discover their defects. It may be answered in general, that every such difference must proceed from what I call the spirit of the government and of the people, which will not only decide as to numbers, but as to many other things. I must however observe, that the question in itself is of little importance, if nothing but numbers be considered; for of what consequence is it to know how many people are in a country, when the employment of them does not enter into the inquiry? Besides, it is only by examining the employment of a people, that I can form any judgment as to this particular. But as the numbers of mankind have been thought a point worthy of examination, I have chosen this title for a chapter, which might perhaps have more properly stood under another. While slavery prevailed, I see no reason to conclude against the numbers of mankind, as I have said already: when slavery was abolished, and before industry took place, if my principles be true that period I think should mark the time of the thinnest population in Europe; for I believe it will be found, that there never was an example of a country, however fertile by nature, where every one was absolutely free; where there was little or no industry, nor labour, but in agriculture; and where, at the same time, there were many inhabitants, not beggars, nor living upon charity. I have mentioned this so often, that I am afraid of tiring my reader with useless repetitions. I have brought it in here, only to give him an opportunity of applying this principle to the solution of the question before us.
