A. Winchell on the Animike in Jvimncscta. 23 
I wish to cite one more instance of the local relation of the 
Animike to the gneissic rocks of the region of Gunflint lake. 
From the western extremity of the northern swell of the lake, 
a distance of two miles west along the northern section line of 
sections 34 and 23 of T. 65, R. 4 W, and then a quarter of a 
mile south along the western line of section 23, brings us to an 
outcrop of the Animike which incloses a heavy deposit of mag- 
netic iron ore. The outcrop is less than a quarter of a mile 
south of a ridge of gneiss which marks the southern boundary of 
the Giant's Range. We find exposed here in a bluff, a bed of 
magnetite about six feet thick, underlaid by eight feet of thick- 
bedded rock of which the upper part is composed of fine grains 
of quartz and orthoclase, with argillaceous matter, and the lower 
part is bluish, finer and more compact; but neither of these 
rocks has been particularly studied. The dij:) here is 13°. In 
the immediate vicinit\- a test pit has been sunk (fig. 4) which

passes through all the Animike beds present and terminates on 
the gneiss. The magnetite here is from three to four feet thick, 
but varies in quality both horizontally and vertically, ending 
downward in a broken, cherty zone. At the plane of contact 
between the Animike and the gneiss is a layer of brown earthy 
matter about four to six inches thick. In places, this appears a 
sheet of Animike rusted and decayed, but the greater part of 
the bed plainly comes from the decay of the gneiss; for it
