magnetite deposit apparently of large extent, in one hole 71 feet 

 of ore was encountered split into two portions by a horse, and in 

 another hole 34 feet of solid ore was found. The ore probably 

 belonged to a single seam, but further exploration will be necessary 

 to clear up the relations. The Harmony mines, the most recent 

 of the Mineville workings, made a good record and will be capable 

 of a large yield when in full operation. Some of the ore now 

 mined can scarcely be distinguished from the rich, coarsely crystal- 

 line magnetite found in the Barton hill group. The latter mines 

 w'ere not actively exploited last year as work was concentrated on 

 the new adit designed to tap the ore bodies in their downward ex- 

 tension. The adit was driven to a point 500 feet north of the old 

 Arch pit, or 1700 feet from the portal. Ore was found in a nearly 

 continuous seam, but of variable thickness, sharply compressed in 

 places and ai^ain swelling out to form a body of good size. The 

 deposits were thus far from exhausted by the early operations. 



Lake Sanford. The exploration of the titaniferous magnetites 

 near Lake Sanford, Essex co. was continued in 1908 with results 

 fully commensurate with anticipations. L'p to October i, 1908 the 

 Tahawus Iron Co., who recently took over the properties, had 

 drilled 26 holes on the Sanford ore body to an average depth of 

 199 feet w^ithout reaching the lower limits of the ore. The avail- 

 able ore in this deposit alone amounts to many millions of tons. 

 Experiments in mill treatment have confirmed the view that a por- 

 tion of the titanium can be removed by crushing and passing over 

 magnetic separators with additional benefit as regards the iron con- 

 tent. A product averaging about 60 per cent iron and not more 

 than 6 or 7 per cent titanium can be made without difficulty. 

 The company has secured a charter for the construction of an 

 electric road which will probably be built from Lake Champlain 

 to Tahawus. An alternative route has been surveyed from the 

 Adirondack branch of the Delaware & Hudson Railroad. 



Lyon Mountain. Owing to the destruction by fire of the new 

 mill early in 1908 the mines at Lyon Mountain did not make the 

 expected output last year. The loss of the plant was critical, in- 

 asmuch as many improvements in the way of a central electric 

 power station, new trackage, etc. had just been completed that 

 should have led to important economies. The old mill was again 

 placed in commission. 



Benson mines. The Benson ]\Iines Co. was operative during a 

 part of the year, but made only a fraction of the output of which
