Page 159 - Meadow," so called, and at the mouth of the inlet near the head is a first-rate place for pickerel. A mile below the meadow you reach the dam, which does not show until you are a few rods from it. The steamer lands at her wharf, beside the road, on the right bank of the river, a short distance above the dam. The boat arrives here at half-past ten, and leaves at eleven. It is met each day by the Androscoggin Lakes Transportation Company's team to convey parties to Dixville Notch.
Page 48 - Tennessee, we find, as the result of multiplied chemical analyses, a progressive increase in the proportion of the volatile matter, passing from a nearly total deficiency of it in the driest anthracites, to an ample abundance in the richest gaseous coals.

Page 98 - It may have occupied only 5000 years, being at a yearly rate of a half a foot to one foot ; but possibly it was two or three times as long. While the slow sinking of the land was taking place, the accumulation of the ice by snowfall may have proceeded at a somewhat more rapid rate, so that the thickness of the ice-sheet and the altitude of its surface were increasing up to a maximum nearly coincident with that of the subsidence. Finally, however, the subsidence brought a warmer climate on the southern...
Page 91 - Chesapeake and Delaware bays were excavated, and erosion was in progress at a far more rapid rate than with the present low altitude of this region. The Lafayette formation seems to me more closely related to the Glacial period and the conditions producing the ice-sheets than to the preceding very long Tertiary era, and for the same reasons which have been well stated by...
Page 93 - This lobe in its maximum extent ended near Des Moines, and its margin was marked by the Altamont moraine, the first and outermost in the series of eleven distinct marginal moraines of this epoch which are recognizable in Minnesota. When the second or Gary moraine was formed, it terminated on the south at Mineral ridge in Boone county, Iowa. At the time of the third or Antelope moraine, it had farther retreated to Forest City and Pilot mound in Hancock county, Iowa. The fourth or Kiester moraine was...

The clay deposit varies from a perfectly clean clay to clayey sand as we go from the deep water of the south to the northern shallows It is generally unstratified, but shows local areas of stratification. Its thickness varies from a few inches to twelve feet at West Bethlehem, but the general average is three feet. The "Packer clay" was thought by Williams to be absent from the part of Saucon Valley west and south of Hellertown.
Page 647 - Society must present to the Treasurer a fully itemized bill, certified by the official ordering it, and approved by the President. The Treasurer shall then pay the amount out of any funds not otherwise appropriated, and the receipted bill shall be held as his voucher.
Page 89 - EW Hilgard in 1855 and 1856. This formation was spread across the valley plain 50 to 150 miles or more in width along an extent of 600 miles from the mouths of the Missouri and Ohio rivers to the Gulf of Mexico, during the closing stage of the Tertiary era and the beginning of the Quaternary, to each of which it has been assigned. McGee, Cliamberlin, and Salisbury hold that it is probably referable to the Pliocene period ; while Spencer...
