DEAR SIR: The ability of our Government to carry on this war depends upon its being able to continue to obtain the enormous amounts of money requisite. Of late, within a week or so, an alarming falling off in the bond subscriptions has taken place. Now it is upon these private subscriptions that the ability of the banks to continue to lend the Government money depends, and unless a change takes place they will be unable to take the fifty millions remaining of the one hundred and fifty millions loan. A member of the committee informed me lately that the banks had positively declined to pledge themselves before the 1st of December, notwithstanding Mr. Chase's desire that they should do so. This sudden diminution of subscriptions arises from the course taken by some of our friends in the West. Even suppose that Gen. Frémont is treated unfairly by the Government (and I think he is fairly termed incapable)--but suppose there should be injustice done him--you might disapprove it, but the moment there is any serious idea of _resisting_ the act of the President, _this_ war is ended. For the bare suggestion of such a thing has almost stopped subscriptions, and the serious discussion, much more the attempt, would instantly put an end to them. I beg to remind you that in what I say I have no prejudice against Frémont. I voted for him and have always concurred in opinions with the Republican party, but we have now reached a point where, if we look to _men_ and not to _principles_, we are shipwrecked. Frémont is not more anti-slavery in his views than Lincoln and Seward, and if he were in their place would adopt the same cautious policy. The state of affairs must be my excuse for intruding upon you these views. We _all_ have _all_ at stake and such a crisis leads those to speak who are ordinarily silent. I remain, my dear Sir, Yours respectfully, M. CAREY LEA. To this weighty communication Trumbull made the following reply: WASHINGTON, Nov. 5th, 1861.
