It is not impossible that there was another, though subordinate, reason. Between Whitehall and Lombard Street communications had been passing from time to time, which might fairly raise the presumption that advantage would be taken of any fresh Act to insert a clause under which all Post Office servants, the postmasters-general included, would be disfranchised. Cotton and Frankland, who still retained their seats, the one for Cambridgeshire, and the other for the borough of Thirsk, were not the men to be deterred by personal considerations from doing what they conceived to be their duty; but if on principle they objected to an increase in the rates of postage, it was little calculated to reconcile them to a measure which they regarded as mischievous that, as a probable consequence of its introduction, they would lose their seats. But be the reason what it might, the fact remains that, whereas at one time they were continually suggesting the propriety of fresh legislation in order to clear up ambiguities in the existing statute, no such suggestion had been recently made, and they now remained perfectly silent. Thus matters stood when, in October 1708, or a year and a half after the Act of Union had passed, an incident occurred which made silence no longer possible. Letters of Privy Seal had been issued granting salaries payable out of the revenue of the Scotch Post Office to certain professors of the Universities of Edinburgh and Glasgow, and warrants for payment of these salaries were sent to Lombard Street to be signed. The postmasters-general, being in doubt whether their signature would be valid, took the precaution of consulting the law officers. The law officers' opinion, which was not given until the end of December, must have struck dismay into the hearts of those who sought it. It was to the effect that the postmasters-general of England could not act as postmasters-general of Scotland until they had been to Edinburgh and taken the oaths prescribed by the Scotch law. A journey to Edinburgh in those days, especially in the depth of winter, was no light undertaking. But this was not all. And as soon--the opinion proceeded--as they have taken the oaths and qualified as postmasters-general of Scotland, they will cease to be postmasters-general of England.
