Clinton, Oneida co. The Rossie Iron Ore Co., the Fair Haven 

 Iron Co. and the Ontario Iron Ore Co., who were active in 1907, 

 made no output last year. 



Mineville. Though there was less activity in mining last year, 

 the properties of both W'itherbee, Sherman & Co. and the Port 

 Henry Iron Ore Co. continued in steady operation. The output 

 of the two companies totaled 502,663 long tons as compared with 

 751.155 long tons in 1907, which was the largest amount hitherto 

 recorded for the district. The Old Bed mines, which include the 

 " 21,"' Joker and Bonanza workings, contributed the larger part of 

 the total, the remainder coming from the Harmony shafts, Smith 

 niine and Barton hill tunnel which belong to W'itherbee, Sherman 

 & Co. 



Despite the contraction of mine output there has been no inter- 

 ruption in the progress of the works of development and improve- 

 ment that were started previous to the depression, and the condi- 

 tions of the properties may be considered as better than at any 

 time in the past. With the return of a normal iron market the 

 companies will be able to profit from an increased output which 

 can be maintained from present ore reserves for several years to 

 come. The combined productive capacity of the two companies is 

 now about 1,000,000 tons a year. 



The principal underground developments during the year were 

 connected with the new shaft of the Port Henry Iron Ore Co. on 

 the "21 " property, and the exploration in the Joker-Bonanza, 

 Harmony and Barton hill mines by Witherbee, Sherman & Co. 

 The shaft sunk by the former company was bottomed at a depth 

 lietween 500 and 600 feet and the ore was encountered within a 

 short di.stancc. It will have a hoisting capacity of 1500 tons a 

 day, more than twice the output formerly secured from the incline. 



The results obtained with the diamond drill in exploring the 

 southerly part of the Joker-Bonanza ground during the past year 

 afforded much new information regarding the form of that deposit 

 and brought to light the existence of another magnetite body below 

 it. In the southernmost sections some change was shown in the 

 shape of the Bonanza-Joker body as previously mapped.^ though 

 the exact modifications can not now be fully stated. Drill holes 

 put down into the foot wall from the workings above revealed a
