From those diplomatic suggestions, which are accordant with _European_ exigencies, Mr. Seward readily turns his attention to Mexican affairs, in a carefully considered and most ably written letter of instructions for Minister Corwin. He touches upon the robberies and murder of citizens, the violation of contracts, and then gracefully withdraws them from immediate attention until the incoming Mexican administration shall have had time to cement its authority and reduce the yet disturbed elements of their society to order and harmony. He avers that the President not only forbids discussion of our difficulties among the foreign powers, but will not allow his ministers '_to invoke even censure against those of our fellow-citizens who have arrayed themselves in opposition to authority_.' He refers to the foreshadowed protectorate in language complimentary to Mexico, yet firm in assurance that the President neither has, nor can ever have, any sympathy with revolutionary designs for Mexico, _in whatever quarter they may arise, or whatever character they may take on_.' Within one week (and at dates which contradict the prevailing gossip of last April, that Messrs. Adams, Dayton, Burlingame, Schurz and Co. were detained _awaiting_ Mr. Seward's advices) still more elaborate and masterly instructions are given out to these gentlemen. The paper to Mr. Adams will in future years be quoted and referred to as a model history of the rise and progress of the secession enormity. It may be asked, Why are such dispatches and instructions needed? Why such elaborate briefs and compendiums required for gentlemen each of whom may have said, respecting his connection with subject-matter of the Secretary (none more emphatically so than Messrs. Adams and Burlingame), _quorum pars magna fui?_ Yet, it must be remembered that diplomacy, like jurisprudence (with its red tape common to both), taketh few things for granted, and constantly maketh records for itself, under the maxim _de non apparentibus non existentibus eadem est ratio_; and ever beareth in mind that when _certioraris_ to international tribunals are served, the initiatory expositions and the matured results must not be subjected to a pretence of diminution, but be full and complete. The early dispatch for Mr. Burlingame contains the caustic sentence, 'Our representatives at Vienna seem generally to have come, after a short residence there, to the conclusion that there was nothing for them to do, and little for them to learn.' But 'the President expects that _you_ will be diligent in obtaining not only information about political events, but also commercial and even scientific facts, and in reporting them to this department.' Although the Austrian mantle was soon transferred to the classic shoulders of Mr. Motley,--another honored Bay-state-ian,--the caustic reference to predecessors, and the implied compliment of request, did not at all lose their respective significance.
