60 TRANSACTIONS OF THE [FEB. 9, 
phosed in places, is tilted up at a sharp angle, aud shows every 
variety, from gray and blue to a fine white statuary marble 
quite equal.to the Carara. Near the summit of Mt. Morris 
I found a vein of quartzite running northeast and southwest, 
showing evidence of galena and stringers of gray copper, but 
without any development worthy of mention. 
From the summit of Mt. Morris the other peaks which to- 
gether form the mass of the East Butte are observed, being 
named respectively Mounts Lebanon, Brown, and Royal. De- 
scending Mt. Morris toward the west and north, the limestone 
collar is soon reached and was followed by me to the north and 
east. 
At the contact between the marble and porphyry on the 
north side occurs an interesting deposit of magnetic iron ore, 
showing, where decomposed at the surface, copper stains, and 
carrying traces of copper at certain spots. The outcrop is from 
forty to fifty feet in width, and extends for seven hundred or 
eight hundred feet in the are of a circle, following the lime- 
stone contact, and has been prospected in a number of points by 
shafts, tunnels, and cross-cuts, indicating a probable permanency 
to a considerable depth. At one point ashaft fifty-four feet deep 
was all in ore, with a cut extending southward for forty feet, all 
in solid magnetite, without, as yet, going through it. This ore 
yields sixty per cent of iron by assay and is low in phosphorus. 
Its location, however, renders it of little value for many years to 
come. From the fact that magnetic bowlders were noticed by 
me on the north side of the mountain and also on the eastern 
slope, [ am ready to believe that this iron-ore bed may be found 
to extend for several thousand feet further than it has been ex- 
plored as yet. 
I had no opportunity to examine the other peaks of the Hast 
Butte, nor to ascend either the Middle or West Butte, but was 
informed by an intelligent miner. that they consisted of por- 
phyry similar to Mt. Morris, with the same dikes of trap, and 
with indications of copper, lead, and gold, but practically un- 
prospected. 
The line of the Great Northern ranning westward from 
Assinniboine will cross the famous Flathead country between 
the main range and the Bitter Root range of the Rockies, over- 
coming the former through the Marias Pass. ‘This Flathead 
country promises remarkable developments in coal, iron, and 
other metals, but is at present almost unexplored, excepting 
around the lake and reservation, and is a paradise for the lover 
of big game. Then turning northward, the line will strike the 
Kootenai River at the point where from its soathern flow it
