The Secretary read the letter, as follows: Lisnon, March 24, 1866.

Certainly I have never been of the number of those wh aodmired the President's roriner " Democracy” in its party sense. but I should feelui sclt' wanting in the heartof atrue American could withhold or see withheld, from him the justice due to such rare devotion ushehas shown, or fail to recognize his proeumnfilninecnhtinsgerlvoiycaelsttyo, othrehUolndiobnacakntdhehgisramspoodfegsrt attitude and aifoction.

The common strong sense of the country will vindicate itself min.as it has oiten done before. by an instruction li cly to be rememberedby thosew 0 would “ rule or ruin.” The people are weary of agitation, merely for thcsake of agitation, and they demand that peace. olerndgetrh and law shall be reestablished throughout the and breadthof the Union. Faction can no more arrest the march of those events than the march of the waves.which will not go so far and no further iit their bidding, though they may command with the tongueof 1,000Uniiutes. Let the Administration ire straight forward and without shrinking and all will bewell, howl as ar tisanship may at its heels. Look at the reco of your own individual expericnce since 1861 if instruo lion and encouragementbe needed. who so perso outed, outraged and truduced, undby many who should hang their headsdown in very shame and who so triumphantly honored and sustained evento the dangerous point of being praised by pelledhomageof murders? Lacom If it were possible to destroythe Uni on and whith it all hopesof the future. the men engaged in and exciting the crusade would be exactly the appropriate instruments. All their endeavors their onthusiusm and their desires have been directed to that end, if not with intention, at least with a mischiovous policT thatit' successfulcould produceno other result. ‘hcy seem to have taken their lessons of wisdom from the Duke of Alva, whose advice, unreason and obstinate conduct cost lfhilip H, one of the fairestpartsof hisdominions. Minus the form of theInquisition of whichthemodernAlvas would preserve iill the punishment thereis a.striking par allel between the champions of harsh and headstrong zeal 300 years agoand that which lashes itself into fury now, and merely because it cannot have "its own way. We are fighting a new battle against foes the more dangerous fof orrtbhcei.nUniine sni.d ionunsd and within the lines of our camp. But I iavo not a particle of doubt about the result. an more than I had about theissue of the OtllefWlflfJ! onour proper strength eould becollected andJudicipusly applied. The crisis demands positive reiuedies and direct treatment. Quackery will kill in this extremity. Therefore the sooner it is understood that the line must be drawn broadly and clearly the soonerWill the Administration be relieved from some of the dancers which incidentally menace it. Whoever has studied the eventsof the war inust be convinced that the black man cared very little for his own ulaluaor was willing to make mm etlort to changeit. No such opportunity was ever offeredto an enslaved racetostri e contMBDIQDeIn’, ough for itself, and certainly on wasgivento it to do soin some directions. Every proper and humane man feels that, emancipated as that racenowis.it shouid hiire every just aid and protection until ableto help itself. But let matell you. from somelittle observation on the subyoctand some knowledge‘of the people. that humaningenuity could not devise a more effectivo method for fastening another form of bondageupon them than this bullet, which is proposed as their sovereign panacea. Give them that right and wbeoufaldir pledge my life on the result. if the testeoul y made. that almost 90%. of the whole black population would vote on the side of their old masters; or in other words, become the in Astnrdumifeonvtes ofhfeadsateyncionmg neesw chains upon themselves. (which I hope neverto see for fear“of the consequenccs)when these peoplemay voteWithout condition. you may expect to see the South compacted by negro mirage and uniting with the northern so culled “Democracy” to regain on session of the Government and overthrow everyting thus far accomplished. And such a result would be quite in keepin With the sngiicity and the moderntion of those who are ready to sacrifice everything sacred to the one idea of their foolish fanaticism. I have not been able to see the immine ncy of awnr Prreisrci does notn, bauct count of the ballot as supposed by the I do see in it the much more serious danger now suggested. The old hatred and jealousy between the negro and the ignorant white class (thntthencgroin his loftlness calls the “ ioorbuckra“) would lead to collision. probably, if they were approached by ‘an equalizing process like suffrage, but cannot ink anything serious would comeof it. The political aspectof the question is muchgravcr, and ought not to be ignored. Of course Frederick Douglass and his followers would argue difierently, but experience is worth a little more than their delusivo theories.
