The political machine that is now in motion, is so vast, and comprehends so many nations, whose interests are not easy to adjust, that it is perhaps impossible for the human understanding to foresee what events may occur to disturb it. But at present there is no unfavorable appearance from any quarter. We are in hourly expectation of interesting news from the English, French, and Spanish fleets, from Petersburg, from London and the Hague, and especially from North America. Every wheel and spring in the whole political system of Europe would have its motions rapidly accelerated by certain news from America, of any decisive advantage obtained over Cornwallis, in South Carolina; so true it is, that America is the very centre and axis of the whole. The death of the Empress Queen it is generally thought will make no alteration in the system of Europe. Yet it is possible after some time there may be changes, none, however, which can be hurtful to us. I have the honor to be, &c. JOHN ADAMS. * * * * * TO THE PRESIDENT OF CONGRESS. Amsterdam, December 30th, 1780. Sir, The Province of Zealand having been opposed to the other Provinces in so many instances, and having lately protested against the resolution of the States-General, which begin to be thought spirited, it may be useful to explain to Congress the causes which influence that Province to a conduct which is generally thought to be opposite to the true interest of the Republic in general. In the States of Zealand there are only five voices, three of which are absolutely in the discretion of the Prince of Orange, who has one voice as Stadtholder of the Province, another as Marquis of Veere, and a third as First Noble. The Stadtholder is therefore absolute in this Province, which accounts at once for its conduct upon every occasion. The friends, however, of the Prince, of England, and of Zealand, are not willing that the world should believe that the Prince's power in this Province, and his attachment to England are the sole causes of its conduct upon every occasion, and therefore they enlarge upon several topics, as apologies and excuses for a behavior, which cannot wholly be justified. The arguments in justification or excuse of Zealand are drawn from four principal sources. First, the situation of the islands, which compose the Province. Secondly, the interests of its particular commerce. Thirdly, the weakness of its interior forces. Fourthly, the state of its finances.
