NEW YORK, Nov. 1O--Deta1lS or the plans of Sim Fein leaders for the insurrection in Ireland which oulminated in the Easter Monday riot of last year, together with ln- formation relative to the landing on the Irish coast of Sir Roger Case ment, were recounted in a communi- cation found in the possession of General Liam Mellows, an Irish revolutionist, arrested here several weeks ago and made public today by William J. Flynn. chief of the United Statee secret service.
 At the same time, Flynn gave out copies of an artfully worded letter which Thomas Welsh, a British sub ject attempted to destroy when taken into custody by federal authorities on the arrival of a steamship here last Sunday.
 The two communications, secret service agents say, have furnished much information of value in their investigation of the ramifications of Sim Fein operations in the United States.
 Mellows, who is said to have com mand of a considerable force of reyolutionists during the Dublin riot, is at liberty under S7,500 bail, charged with obtaining by fraud a seaman's passport on which it is al legged he intended shipping on an English bound vessel in order to as sist in another Irish rebellion.
 That another uprising was planned for time not distant, is indicated, authorities believe, by a closing sentence in the unaddressed letter found in Welsh's possession. In urg- ing discretion in the wording of communications. presumably from Sim Fein agents in the United to leaders of the movement in Ire land. this letter said:

 The word "Seanfear' recurs a number of times in the communica- ton, which was of considerable length and written in a smooth, Yegular hand. william Cain Mrs. Cuuan." Tommy O'C," Liam and persons designated by the letters M. W" 'M." and 'L." are men -ioned in the communication. Ref erence is also made to a man who the letter indicates, posed as a priest when that role best suited his pur- pose and to another person referred to a '1ady who was recently re- leased"
 Through study of the communica- ton federal authorities believe the person designated as "Seanfear" is the director of all Sim Fein opera tions Though unsigned the wording of the letter, they believe. shows il was written by a subaltern of Sean fear who might be termed the "sec' retary of state" of the Sim FeiI organization.
 Portions of the letter, authoritie: say, give ground for their belief tha Welsh was one of a number of mes sengers who brought orders iron leaders of the organization in Ire land to their agents in this countr! and returned with word as to thu progress of operations here. Welsl is in the Tombs in default of $2,50 bafl, charged with violating tn trading with the enemy act.
 In requesting that some brooches be purchased with money which h was sending. the author of the Welsl letter wrote:
 The wonans' society wants t know if it would be possible to hay a supply sent out here. They vii guarantee a sale of 100 pounds. An profits from the sale will be hande over to the arms fund
