Moody quarry (Plate IV, 76)

A quarter of a mile south of the Frost quarry, about 1 mile south of Davis, Leslie Moody has been working a pegmatite dike containing orthoclase, quartz, and black mica. The quarry has followed the dike for 80 feet along the strike which is N. 20° E. and 40 feet into the hill side where it has a face 15 feet high. At the top of the face is granite gneiss with a low dip into the hill, indicating that the deposit is a thick lens with an easterly dip. The rock is weathered and friable toward the top and 8 feet of gravel spar has been stripped for a distance of 40 feet beyond the southwest end of the quarry.

Shipley quarry (Plate IV, 77)

A quarter mile south of Davis on the Mollie Shipley place is a quarry 100 feet long by 50 feet wide, and 40 feet deep that was formerly worked by John Cummins and from which John Weetenkamp took about 8 carloads of feldspar monthly from his farm one-half mile east of Woodstock in 1917. There are two openings on dikes striking northeast, one 50 feet long by 15 feet wide by 20 feet deep, the other about 100 yards to the south is 50 feet long by 30 feet wide by 20 feet deep. The workings are in loose weathered outcrop rock and yielded a whitish gravel spar. The output was shipped from Woodstock to the Eureka Mining and Operating Company.

Brown quarries (Plate IV, 79)

One mile southeast of Woodstock on the farm of Mrs. Frank Brown are a number of shallow openings that produced feldspar for 2 or 3 years over 15 years ago. They were worked by Frank Brown and John Cavey. The largest opening is a narrow east-west trench 150 feet long. The nature of the débris about the openings indicates that they were gravel spar deposits.

Baltimore Feldspar Company quarries (Plate IV, 80)

The Baltimore Feldspar Company quarried a small amount of feldspar at several places on a property on which they had more extensive flint quarries about 1 mile northwest of Woodstock. A large amount of

feldspar had previously been taken from this property by William Theis from numerous small shallow openings that yielded chiefly gravel spar.

Quarry near Marriottsville (Plate IV, 81)

John Weetenkamp took out a few carloads of feldspar over 10 years ago from a small opening a quarter of a mile east of Marriottsville on the property of Wade Warfield.

Warfield quarry (Plate IV, 82)

A larger quarry on the property of Wade Warfield on the west side of Marriottsville was worked by John Weetenkamp. The opening is 150 feet long in the direction parallel to the creek. No work has been done for over 10 years and the caving of the overburden has covered the rock. The quarry is located on the westerly one of the two westerly-dipping dikes that run parallel to the creek more or less continuously for a distance of 2 miles south of Marriottsville on either contact of a belt of limestone that underlies the valley of the creek. The next 7 quarries described are located on one or the other of these dikes. Much of the feldspar that was used by the fertilizer companies in the vicinity of Baltimore during the war came from quarries located on these dikes.

Product Sales Company quarry (Plate IV, 83)

One mile south of the Warfield quarry on the Pete Zepp farm the Product Sales Company worked a quarry on the same pegmatite belt that was originally opened by John Weetenkamp. The opening is 150 feet long and the dike has a width of 20 to 30 feet.

Baugh and Sons Company quarry (Plate IV, 84)

The most extensively worked of these quarries was that on the Marcellus Wright farm 11⁄2 miles south of Marriottsville, leased by the Baugh and Sons Company fertilizer manufacturers and operated for them under contract by H. O. Firor. The property was leased in January, 1914, by Sarah G. Mitchell and subleased in October, 1915, to the Baugh and Sons Company who took out over 10,000 tons of feldspar. At first the rock was used at their own plant for its potash content but later the

company ceased using feldspar and sold its output to Golding Sons Company. For a while operations were conducted on a large scale, a steam shovel was used, a force of 12 or more men employed at the quarry, and 3 motor trucks and 3 teams engaged in hauling the stone to Marriottsville for shipment. Recently John Hackett took out a few car loads of second-grade spar which he sold to the Seaboard Feldspar Company.

The dike has a strike N. 25° E. and a steep westerly dip. It has been worked 250 feet along the strike with a face 40 feet high and 30 to 40 feet into the hill. As the dike is not over 30 feet wide, the quarry face has more than 25 feet of hanging wall schist overburden. The footwall of the dike is limestone. The feldspar is nearly white in color, carries less mica than most of the deposits of the region, and has yielded potterygrade rock with less hand sorting than is usually required. One thousand tons of the rock used for fertilizer purposes is stated to have averaged 10 per cent potash which is a surprisingly high potash content for a feldspar so light in color from this region.

Quarry near Marriottsville (Plate IV, 85)

John Weetenkamp opened a quarry on the Wade Warfield property at the south edge of Marriottsville in the pegmatite zone paralleling the limestone valley on its east side which he worked for a while in 1916. An opening was made on each side of the county road, the deposit extending under the road, and the larger opening on the west side is 30 feet in diameter and 20 feet deep. The feldspar is of light-buff to cream color.

Zepp quarry (Plate IV, 86)

The pegmatite belt continues along and under the county road from the quarry last described to a second opening a half mile farther south on the west side of the road which was made by John Weetenkamp in 1916 and is located on the Pete Zepp farm. The quarry is 50 feet long, has a face 25 feet high, and has been worked into the hill toward the road more than 20 feet without reaching the opposite wall of the dike.

Mathews quarry (Plate IV, 87)

On the continuation of the same belt, 1 mile south of Marriottsville, John Weetenkamp worked a quarry on each side of the road in 1915. That on the east side, owned by George Mathews, is 100 feet long, has a face 20 feet high, and has been extended 30 feet into the hill slope without cutting through the dike. The other, on the Marcellus Wright farm, has been worked for 50 feet along the strike lower down on the dip of the same dike.

Wright quarry (Plate IV, 88)

Another quarry that has been opened on this dike lies a quarter of a mile farther south, immediately back of the Marcellus Wright house. The dike outcrops here as a small knoll with a width of 30 to 50 feet. Years ago William Theis worked this quarry and later John Weetenkamp took out a small amount of stone.

Harold Stromberg quarry (Plate IV, 89)

One mi'e southwest of Marriottsville on the Harold Stromberg farm is an old feldspar quarry 50 feet long, 30 feet wide, with a 20-foot face from which a highly micaceous feldspar containing white mica was quarried. About 2 years ago Albert Sandusky shipped 20 carloads of No. 2 grade from it.

Albert Sandusky quarries (Plate IV, 90)

A quarter of a mile west of Marriottsville on the Wade Warfield property, Albert Sandusky has been working feldspar for several years. The westerly of the two quarries produced 2,800 tons of first and second grade feldspar about 4 years ago. The opening followed a dike in the direction S. 30° W. into the hillside until the face was 30 feet high. The sides have caved and the dike is no longer exposed.

One hundred yards to the east, on the opposite side of a small ravine, is the opening that is being worked now. The quarry is 50 by 20 feet and 15 feet deep and is on a dike which strikes N. 40° E. and dips to the west. The east wall, or footwall side of the quarry, is fine-grained pegmatite of granitic texture. The west wall is mica schist. The
