" Ore from a vein cutting crystalline limestone, and running 

 N. 60° W. The vein has a thickness of from six to twelve inches, 

 and is composed of calcspar, in which the galena is disseminated 

 .in lumps, which, in a trial shaft of about fifty feet, sunk in 1854, 

 on the land of Mr. Buel, were sufficient to pay the expenses. The 

 largest of these lumps may have been five or six inches in width. 

 A counter-lode diverges from the main one near the shaft, and 

 in this neighbourhood, there occur four additional lead-bearing 

 veins, running parallel with the main one, all contained in a 

 breadth of about 1000 feet. They run obliquely across the lots,, 

 and thus intersect the lands of several proprietors. On lot four 

 of the same range, Messrs. Foley and Co., of Montreal, have sunk 

 a small shaft on one of the lodes. — Laurentian,^^

" Ore from one of five nearly parallel lodes cutting crystalline 

 limestone, in a breadth of about a quarter of a mile, on the proper- 

 ty of Mr. Weston Hunt, of Quebec. The gangue of the lode is 

 a mixture of heavy spar and calcspar. About a mile to the east- 

 ward of these, are other nearly parallel lodes, also cutting crystal- 

 line limestone, on land belonging to the same proprietor. Shallow 

 trial shafts were many years ago sunk on some of these, but what 

 quantity of lead-ore was obtained in them is not known. On lot 

 13, range 5, of Bedford, Messrs. Foley & Co., of Montreal, have 

 sunk a trial shaft to a depth of fourteen feet, on a lead-bearing 

 lode of six inches, of which the gangue is heavy spar. It cuts 

 crystalline limestone, and reaches gneiss, and in both rocks shows 

 good bunches of ore. This lode is about three miles south-west 

 from those first mentioned, and runs parallel with them. — Lau-

"N.B. — The distance between the Lansdowne and Bedford 

 lodes is about twenty -five miles ; they bear for one another, and 

 it appears not at all improbable that the veins in the two locali- 

 ties may be identical, or belong to one group. If a line from 

 the Bedford to the Lansdowne lodes were continued twenty-five 

 miles farther, it would cross the St. Lawrence, and strike Rossis 

 in St. Lawrence County, New York, where a well known group
