Сторінка 645 - And there went forth a wind from the LORD, and brought quails from the sea, and let them fall by the camp, as it were a day's journey on this side, and as it were a day's journey on the other side, round about the camp, and as it were two cubits high upon the face of the earth.

Сторінка 21 - Hence marriages in America are more general, and more generally early than in Europe. And if it is reckoned there, that there is but one marriage per annum among one hundred persons, perhaps we may here reckon two ; and if in Europe they have but four births to a marriage (many of their marriages being late), we may here reckon eight, of which, if...
