The results of test of manganese froro vein recently opened near ,,.,a have been most gratifying to -. narties directly interested, as well -o those in Mena who have long ,aoge8 forward to development in this direction. At meeting of the members of ,hs executive committee of the Con-

 To the Mena Commercial Club, Mena,
 Ark
 gentlemen:-Your committee ap- pointed to witness a mill test of man ganese ore taken from the property of the Manganese Mining X Develop ment Company, beg to submit the fol- lowing report;
 Your committee went to the proper ty of the said company and obtained quantity of the ore, which to your committee appeared fair represen- tative sample; the ore was sacked, sewed and sealed under the supervis- ion and direction of the committee, and expressed to the committee at Joplin, Mo. Your committee was noti~ fed that the test was to be made on the 18th day of August Accordingly the committee, excepting MT. Tomlin- son. left Mena on the evening previ- ous, and upon their arrival at Joplin Mir. Graham of the committee accom- panied drayman to the express of- fee, secured the ore and accompanied same to the laboratories of A. Schwarz, consulting engineer, under whose supervision the test was made. Tie ore sacks arrived intact. The seals were broken by MT. Graham of the committee and the ore dumped apon pile from which a quantity of tbe ore was taken for the test, after same was first mixed so as to secure uaiformity for the test.
 The ore taken for the test was first weighed. and then run thru crusher, after which it was screened and run thru crushing rolls, after which it was again weighed and then fed into a jig. The jigging process separating the ore from the rock with which it IS associated in it's natural formation as tahen rom the mlne.
 The operation witnessed by your committee demonstrated to our satis- faction that
 tD The ore can be crushed and reduced thru crushing and the rolls to a size of 3-8 inch and smaller.
 t2l That in the crushing process the ore is separated or brokAn off from the associated rock.
 tSl That the iigging process will separate the ore from the rock, leav- ing the rock practically free from the ore m a form called "chats" or "tail- mgs," and that the ore is practically Tree from the rock as delivered from the jig,
 I4 That the separation of the ore rom the rock by treatment with srsshers, rolls and jigs is feasible and practical.
 Your committee was informed by Ae consulting engineer, MT. Schwarz, sAat the product obtained by this Aethod of treatment of the ore se- cared by your committee as sample x marketable, commercial product; eat manganese ore so treated, clean ca and produced is a high grade ore Tor which there is a ready market and al a price that would render mining 4Ad milling very profitable enter pflse. MT. Schwarz further stated that Ae ore can reasonably be produced at cost not exceeding $15.85 per ton Vi concentrates and that the grade of " so produced would command
 hrket price of $78.50 per ton or bet ~s, based on the sample treated.
 Tour committee being informed s, sAt the test could not be completed snat day. and that the necessary as- says for complete report would not v obtained for at least three days, agreed to leave the completion of the 'est Tn the hands of Mir. Schwarz. ~ Sith instructions that his findings sAOuid be submitted in writing. Ac- .g'luoingly copy of his report is here With submitted
