Brown in Kansas some two years aj|p, and was led by the representation of Brown to join his hand, not knowing at the time what would be the tiel-l of their operations. After some time had elapsed Brown informed him that the town of Harper’s Ferry was the place he contemplated making his stand at. and tlfcit he wished him (C -ok) to proceed there and try and ascertain whether or not the man Forbes had divulged the plan to any one at Harper’s Ferry, as a rumor had reached him to that effect. Cook strongly objected to any such move as contemplated, but was replied to by Brown, that he had taken the oath to stand by him, and that he must not now desert him. Cook therefore started for tin- Ferry ami took up his resilience. After having been there somctim^ .ted he was introduced into society, which resulted' ail- in his courting and marrying a Miss Kennedy, of South Bolivar. He then determined by all possible means to change the determination of ,,!d Brown, but all his arguments and entreaties failed when brought to bear against the iron-wili of the Kansas outlaw.fhe more important portions were thoseivceiril-l»y.Mind,rty-•onon.’an1011md•anre 1 .ia,287r.-ming-thcles.ipe-tingtion'fhe more important portions were tin which tol l of the Convention held in Canada, at 00 54) 00 •)•) 00) 87 5 7084I 74) 584 42 i GO[ 08 ) 70S 85 7 82I 03Vdn,heret \V(Jpulpthe jr.—theKill vTheroke id in•alti-natevhieh the well-known Coii*titut:on was framed; -f the military training under Slovens which Brown’s party went through, altering their -riginal intention, which was to be instructed by C l.

Cook said that the time of the invasion would have been different but for the information given bv Col. Forbes.Before '.lie case of Cook was taken up this morning, Goo. Sennutt, Esq., the counsel of Copeland, appeared and read a number of bills of exception, which he desired the court to take into consideration, although lie felt sure from the former action of the Court that it was of but little avail. Ilis duty to the prisoner, however, demanded that he should go throughall the forms, even if the substance of justice was denied. One of the bills created considerable merriment during its reading, it being •'illed with denunciations of the verdict rendered. The adjectives were put in in profusion, and tlm effect wau to bring the counsel reading them into a position of ridicule.from nl t., .men alsodlorgunl theTlo-Feh-Nn-rcon gent v atheyTHE CASE or COOK.After the proceedings in the case of Copeland had been gone through with, the. case of John F..
