 The Images appearing here are the best quality 
 possible considering the condition and legibility 
 of the original copy and in keeping with the 
 filming contract specifications. 
 
 Original copies in printed paper covers are filmed 
 beginning with the front cover and ending on 
 the last page with a printed or illustrated impres- 
 sion, or the beck cover when appropriate. All 
 other original copies are filmed beginning on the 
 first page with a printed or illustrated impres-

 This specimen is from an important deposit of ore oceumnf>- 
 on tlie west side of the East River, in slates and quartzites of 
 Upper Silurian age. The lode ranges in thickness from ten to 
 twenty feet, with occasional side veins. Fi-om a single pit which 
 was sunk to a dentli of thirty feet on the lode, about fifty tons 
 of ore were obtained. A specimen examined by Dr. T. E. Thorpe 
 of the Andersonian IJniveisity, Glasgow, contained.

 The proximity of the Pictou coal lield adds greatly to the 
 value of this and other deposits of ore in the vicinity of the East 
 River. — Upper Silurian. 
 
 R. H.— Specimen of Red Hematite. 
 
 From what is known as the "Great Red Hematite Bed of 
 McLellan's Mountain," an interstratified bed of ore occurring in 
 slates and quartzites. The following analysis of a specimen of the 
 ore is by ])r. Stevenson MacAdam of Edinburgh :

 The ore has been found to vary in widtli from fifteen to 
 thirty feet, the angle of dip ranging from 2.")^ to 7o°. The specimen 
 is from about the centre of the area, where a section showed fifteen 
 feet four inches of ore of uniform quality. — Lower He/derbenj 
 formation, Upper Silurian.

 B. H.— Specimen of Fibrous Limonite. 
 
 The deposit from which this specimen was obtained has been 
 traced along the north bank of the East Branch of the East River, 
 from Springville to a point seven miles higher u{). Several open- 
 ings have been made, and the lode proved to vary in thickness 
 from six to about twenty-two feet. The follow'ng analysis (Rept, 
 of the Geol. Survey, 1878-74, p. 238) shows the ore to be of 
 excellent quality :

 Tiimestone suitable for a flux occurs in the iimuediate vicinity 
 of the ore, and there are several coal mines in active operation only 
 a few miles off. — Junction of the Upper Silurian and Carboniferous. 
 
 B. H.— Specimen of Compact Limonite. 
 
 On the banks of a small stream near the West Brancli of the 
 East River a band of quartzite inteisected by numerous reticulating 
 veins of limonite is exposed. The veins are for the most [)art very 
 thin, but there is one with a thickness of three feet. Judging from 
 the rmmer-ous masses of 01 o scattered over the surface for a con- 
 siderable distance from the stream, there is some reason to suppose 
 that the deposit will prove of economic value. " The ore is most 
 favorably situated, having near it abundance of wood, water, and 
 limestone, while the Intercolonial Railway passes within a few 
 yards of the area."

 According to an analysis by Dr. T. E. Thorpe, of Glasgow, the

 S.— A Specimen of Spathic or Sparry Iron Ore. 
 
 From an irregular bed occurring in sandstones of the Mill- 
 .stone-grit formation. The ore is crystalline, and, where unacted 
 upon by the weather, of a light grey colour. A specimen, evidently 
 -somewhat weathered, contained as follows (Report of the Geolo- 
 gical Survey, lcS66-69, p. 442.)

 The bed has been traced for several hundred yards, and where 
 exposed in the bank of a brook has a thickness of about ten feet. 
 According to Dr. Dawson its mode of occurrence is not unlike that 
 of the non-tossiliferous sub-crystalline limestones found in some 
 parts of the Lower Carboniferous series associated with gypsum. 
 This bed is only four miles from the Vale Co\\\QXY.—Millstone-grlt 
 formation, Loiver Cavhonifevous.
