The ore in places is a compact rich magnetite, yet the greater por- 

 tion as exemplified by sampling the deposits consists of disseminated 

 grains or stringers of magnetite in a gangue of hornblende, biotite 

 and quartz. Apatite shows in some specimens. The analyses, 

 however, indicate a phosphorus content that is well within the 

 Bessemer limits. The following were made by Mr James Brakes, 

 probably from selected material.

Battie mine. This is located on a continuation of the Cook ore 

 body, about 1 J miles north of that mine. From Emmons's account, 

 the existence of two parallel deposits is inferred, though only one 

 is shown by outcrop or workings. The mine was last operated 

 about 50 years ago. It is an open cut about 600 feet long and 10 to 

 20 feet wide. The ore shows much variation across the dip, bands 

 of massive magnetite alternating with rock that carries a greater 

 or smaller proportion of magnetite in disseminated grains. It has 

 a sheeted structure evidently due to slight movements along the 

 walls. They are noticeably grooved and polished. The principal 

 gangue mineral is biotite. The ore is said to have yielded good 

 iron, similar in quality to that made from the Cook ore. Its gen- 

 eral character is shown by the analyses below which have been 

 communicated by Mr J. N. Stower. The analyses were made by 

 James Brakes from samples taken at different places along the 

 outcrop. The high titanium, reaching over 2 per cent in No. 5, is
