Other localities in this vicinity where lignite was reported by responsible persons, but which were not personally visited by a member of the Survey staff, are as folows:

The Anderson homestead, Township 139, Range 100, Section 24, sixteen feet of good coal reported to have been found in a well twenty-two feet below the surface.

On Paddy creek, a tributary of the Little Missouri, four miles north of Sully spring, lignite in eight and ten-foot seams.

On Government creek, a tributary of the Little Missouri, excellent lignite seams.

One mile west of Belfield, on the south side of the Northern Pacific track, a seam of some importance is slightly exposed, its total thickness being undetermined.

LIGNITE DEPOSITS OF HETTINGER COUNTY

summer.

A limited area only in Hettinger county has been studied, the greater part of the large area included within its limits being necessarily reserved for the field work of the coming From New England as a center work was carried on up and down the north fork of the Cannon Ball for ten miles in each direction, south along Coal Bank creek, a tributary of the stream just mentioned, and just across the line in Billings county, in the Rainy buttes. The country between Dickinson and New England was twice traversed by different routes and observations with reference to lignite were made. The region is marked by a few high buttes, by one or two elevated plateaus of the same elevation as the low buttes which are plainly remnants of these and similar plateaus, and by extensive nearly level stretches in the valleys of the present streams.

buttes

The Rainy Buttes are large, flat topped buttes of the Sentinel butte type already described, and the stratigraphic series that they dislose is nearly identical with that of the other high in Billings county. East Rainy Butte with its outliers. occupies nearly two-thirds of a township, while the top includes an area one-third as great. The upper half is steep, the last fifty feet nearly vertical, the total height above the surrounding

country amounting to 400 feet, its elevation above the Cannon Ball river reaching 460 feet.

Lignite About New England.-The Laramie as exposed on the Cannon Ball at this postoffice consists of sand and sandstone, but two miles north of the river lignites and clays are found. The bank from which most of the coal for New England is obtained is that of Jacob Riess, in Township 136, Range 97, Section 22. Here a seven-foot seam of good coal is laid bare by stripping off four feet of clay. Large springs issue from the lignite. The seam is exposed along the edge of the hill where the bank is located for 300 feet. An analysis of dried lignite from this bank gives:

Lignite from this bank sells for 50 cents a ton at this mine. On John Ermintrout's ranch, six miles northwest of New England, lignite is mined by stripping. His bank shows:

Along the Cannon Ball,, west of New England, are some excellent lignite exposures. Five and one-half miles west of this postoffice the following section is beautifully exposed in a cut bank:

This exposure is continuous for 300 feet. A little lignite has been taken from this point by neighboring ranchmen.

Three miles farther west, under similar conditions, this series. is practically repeated, and the persistence of the seams to this point may be assumed.

On Coal Bank creek, which rises eight miles south of New England, and flows northeast into the north branch of the Cannon Ball, lignite outcrops at a number of points and large springs and areas covered with scoria, both certain signs of the presence of lignite, occur. One four-foot seam of good lignite may be found four miles from the mouth of the creek, twenty feet above water level. Little prospecting has been done along this creek, or along the river farther east, and there is strong probability that an abundance of lignite will some day be brought to light.

Along the south fork of Cannon Ball river lignite is said to abound. Some excellent seams are reported on Grand river, just over the line in South Dakota.

LIGNITE DEPOSITS OF EMMONS COUNTY

Emmons county lies within the drift-covered area, and natural exposures that would reveal lignite seams are not common, except along the Missouri river, which forms its western boundary.

Near Livona,, which is on the river, twelve miles south of Bismarck, some mining has been done. In Township 135, Range 75, the C. H. Edick mine has developed a seam two and one-half feet thick The outcrops occurred near the bottom of a coulee, and the lignite is won by drifting. At the mine the
