The test hole shows that the bed exposed at Sterling Station extends thus far in undiminished thickness. There is no noticeable change also in the character of the ore. A sample of the drill core was analyzed by E. Touceda with the following results:

Martville, Cayuga co. The site of this drill hole is on the west bank of Sterling creek about 15 rods below the bridge at Martville, on the property of Dr John Chapman. The locality is 3 miles southeast of Sterling Station and 5 miles northeast of Red Creek.

This section seems to establish that the ore body which stretches across Wayne county and as far east as Sterling Station, Cayuga co., terminates practically near the latter locality. The excavations made by the Fair Haven Iron Co., at Sterling Station, give some indications of a wedging out of the ore toward the east, though from the evidence here it does not follow that this is anything more than a local condition. The ore bodies are everywhere subject to moderate variations in thickness, but the pinches are usually succeeded in turn by bulges that maintain the average. There is no other

locality, so far as has been determined, where a thick bed diminishes in such short distance to a thin seam.

South Granby, Oswego co. The site of this drill hole is on the farm of Alonzo Lutentelly, I mile southwest of South Granby, and 11⁄2 miles north of Little Utica, on the west side of the highway leading north from the latter place where it is crossed by a small stream.

Dark shale, full of fossilsRochester horizon.

Impure limestone with fossils. Shale with a little limestone. At 76 feet is a 1 inch band showing dark pebbles with pyrite.

Shale quite free from limestone bands. At 101 feet there is a thin seam of ore and the shale contains for 4 inches numerous crystals of pyrite. At 102 feet there are 4 inches of limestone with large brachiopods.

Shale with some very dark bands towards the base.

Light colored limestone with fossils. Near the middle the fossils are replaced by iron ore.

Calcareous shale.

This band of ore is richest below, grading into a highly colored shale above with thin seams of

ore.

Shale with band of limestone at the middle.

Coarse, light colored limestone. Coarse, fossil limestone with some shale.

Lean fossil ore.

Gray compact limestone and alternations of lighter colored limestone and shale.

Gray shale with bands of limestone. The limestone bands include a number of the pearly layers; also some fine compact bands. None of the bands of limestone are over 6 inches thick. Oolitic ore with some fossils at base.

Mottled shale with bands of limestone. One inch of shale with pebbles found 2 feet below the ore. Mottled appearance of shale due to organic remains.

The hole is about midway between Sterling Station and the west end of Oneida lake, an interval that seems to be barren of workable deposits. More tests are needed, however, to demonstrate their entire absence, since the distance to the Martville locality is 10 miles and to Brewerton, the next drill site to the east, about 12 miles.

Brewerton, Onondaga co. The drill was set up on the south shore of Oneida river, within the village, about 75 yards west of the bridge. This point is very near the Oswego-Onondaga county border and the south line of the route followed by the new Barge canal.

Olive-gray shale with many dark bands in the lower part and with few thin bands of limestone. At 19 feet there is a 4 inch band with black pebbles.

Fossil ore, inclosed in shale.

Shale with limestone bands 3 to 4 inches thick found at quite regular intervals. The limestone contains cavities lined with crystals. Traces of ore, as threadlike veinlets, are found in the limestone.

Shale with thin bands of limestone that probably represent the pearly layers. Trace of ore at 133 feet.

Oolitic ore.

The layers below the ore are quite variable. The 2 inches immediately below the ore is shale; then follows a sandstone or conglomerate, becoming coarser toward the bottom.

This section is similar to the one at South Granby in showing two ore seams separated by many feet of rock. The absence of limestone is a striking feature and serves to connect this section with the eastern development of the Clinton, as exemplified in Oneida and Madison counties, rather than the western belt. This is further indicated by the oolitic structure of the lower ore seam.. The 16-inch bed is solid ore of uniform character. It will repay

further exploration. The site of the hole was chosen purely for convenience, and the chances are very remote that the thickest portion of the bed was encountered by the single test. The discovery is thus of considerable potential importance. The ore was sampled by taking a longitudinal section of the core and an analysis by E. Touceda gave the following percentages.

Lakeport, Madison co. The site of this drill hole is 11⁄2 miles northeast of Lakeport on the farm of Robert Cowen. The drill was placed near the spring south of the highway, a little more than 4 mile distant from the shore of Oneida lake.
