But is it certain that Walpole did not know of the existence of this secret treaty? It is certain now that if he did not know of it he might have known. Other English statesmen of the day did know of it--at least, had heard that such a thing was in existence, and were or might have been forewarned against it. Professor Seely puts it beyond doubt that the family compact was talked of and written of by English diplomatists at the time, was believed in by some, treated sceptically by others. The Duke of Newcastle actually called it by the very name which history formally gives to the arrangement made many years after and denounced by Burke. He speaks of "the offensive and defensive alliance between France and Spain, called the _pacte de famille_." Is it likely, is it credible, that Walpole had never heard of the existence of a compact which was known to the Duke of Newcastle? Archdeacon Coxe, in his "Life of Walpole," contends that Newcastle was not by any means the merely absurd sort of person whom most historians and biographers delight to paint him. "He had a quick comprehension and was a ready debater," Coxe says, although without grace or style. "He wrote with uncommon facility and great variety of expression, and in his most confidential letters, written so quickly as to be almost illegible, there is scarcely a single alteration or erasure." But certainly Newcastle was not a man likely to keep to himself the knowledge of such a fact as the family compact, or even the knowledge that some people believed in the existence of such an arrangement. For ourselves, we are quite prepared to assume that Walpole had heard of the family compact, but that it did not disturb his calculations or disarrange his policy. From some of his own letters written at the time it is evident that he did not put any faith in the abiding nature of family compacts between sovereigns. More than once he takes occasion to point out that where political interests interfered family arrangements went to the wall. As to the general rule Walpole was quite right. We have seen the fact illustrated over and over again even in our {34} own days. But Walpole appears to have overlooked the important peculiarity of this family compact; it was an engagement in which the political interests and the domestic interests of the families were at last inextricably intertwined; it was a reciprocal agreement for the protection of common interests and the attainment of common objects. Such a compact might be trusted to hold good even among Bourbon princes. On the whole, we are inclined to come to the conclusion that if Walpole knew anything about the compact--and we think he did know something about it--he was quite right in not allowing it to disturb his policy of non-intervention, but that he was not quite sound in his judgment if he held his peaceful course only because he did not believe that such a family bond between members of such a family would hold good.
