Notwithstanding this, I can give you the strongest assurances that the women of America make the most faithful wives and the most attentive mothers in the world; and I am sure you will join me in opinion, that if a married man is made miserable only _one_ week in a whole year, he will have no great cause to complain of the matrimonial bond.

I send it you now, because I apprehend some late accidents are likely to revive the contest between the two countries.

"The reasons given by the Assembly to the governor for the refusal are, that they understand the act to mean the furnishing such things to soldiers only while on their march through the country, and not to great bodies of soldiers, to be fixed, as at present, in the province; the burden in the latter case being greater than the inhabitants can bear; that it would put it in the power of the captain-general to oppress the province at pleasure, &c.

The sovereignty of the king is therefore easily understood.

And if youth has less of that prudence which is necessary to manage a family, yet the parents and elder friends of young married persons are generally at hand to afford their advice, which amply supplies that defect; and, by early marriage, youth is sooner formed to regular and useful life; and possibly some of those accidents or connexions, that might have injured the constitution or reputation, or both, are thereby happily prevented.

Would you have me give them to, or drop them for a stranger I may find next Monday in the Church of Notre Dame, to be known by a rose in his hat? You yourself, sir, are quite unknown to me; you have not trusted me with your right name.

If one might indulge imagination in supposing how such a globe was formed, I should conceive, that all the elements in separate particles being originally mixed in confusion, and occupying a great space, they would (as soon as the almighty fiat ordained gravity, or the mutual attraction of certain parts and the mutual repulsion of others, to exist) all move to their common centre: that the air, being a fluid whose parts repel each other, though drawn to the common centre by their gravity, would be densest towards the centre, and rarer as more remote; consequently, all matters lighter than the central parts of that air and immersed in it, would recede from the centre, and rise till they arrived at that region of the air which was of the same specific gravity with themselves, where they would rest; while other matter, mixed with the lighter air, would descend, and the two, meeting, would form the shell of the first earth, leaving the upper atmosphere nearly clear.

obstruction in the pores or passages through which it used to ascend to the surface, becomes, by such means, preternaturally assembled in a greater quantity than usual into one place, and therefore causeth a great rarefaction and intumescence of the water of the abyss, putting it into great commotions and disorders, and at the same time making the like effort on the earth, which, being expanded upon the face of the abyss, occasions that agitation and concussion we call an earthquake.

There may be whirlwinds of both kinds, but from the commonly observed effects I suspect the rising one to be the most common: when the upper air descends, it is, perhaps, in a greater body, extending wider, as in our thunder-gusts, and without much whirling; and, when air descends in a spout or whirlwind, I should rather expect it would press the roof of a house _inward_, or force _in_ the tiles, shingles, or thatch, force a boat down into the water, or a piece of timber into the earth, than that it would lift them up and carry them away.
