Seite 72 - ... in the synclines on either side furnished little or no gas, but in many cases large quantities of salt water. Further observation showed that the gas wells were confined to a narrow belt, only one-fourth to one mile wide, along the crests of the anticlinal folds. These facts seemed to connect gas territory unmistakably with the disturbance in the rocks caused by their upheaval into arches, but the crucial test was yet to be made in the actual location of good gas territory on this theory. During...
Seite 72 - I found that every one of them was situated either directly on or near the crown of an anticlinal axis, while wells that had been bored in the synclines on either side furnished little or no gas, but in many cases large quantities of salt water. Further observation showed that the...
Seite 36 - The flame should be fully 20 cm. high when burning free, and the determination should be made in a place free from draughts. The upper surface of the cover should burn clear, but the under surface should remain covered with carbon. To find Volatile Combustible Matter, subtract the per cent.
Seite 71 - Pittsburg parties to make a general investigation of the natural gas question with the special object of determining whether or not it was possible to predict the presence or absence of gas from geological structure. In the prosecution of this work, I was aided by a suggestion from Mr. William A. Earseman, of Allegheny, Pennsylvania, an oil operator of many years...
Seite 64 - While two of the five sections into which the congested value district is divided involve only a mild conflagration hazard within their own limits, they are badly exposed by the others in which all elements of the conflagration hazard are present to a marked degree. Not only is the hazard extreme within the congested value district, but it is augmented...
Seite 1 - Rate of recession of Niagara Falls, accompanied by a report on the survey of the crest, by W. Carvel Hall.
Seite 36 - Determination of Volatile Combustible Matter. " Place i gramme of fresh, undried, powdered coal in a platinum crucible weighing 20 or 30 grammes and having a tightly fitting cover. Heat over the full flame of a Bunsen burner for seven minutes. The crucible should be supported on a platinum triangle with the bottom from 6 to 8 cm.
Seite 37 - The two following causes were suspected, both of which were found to be partly responsible for the difference: (1) Mechanical loss due to the throwing out of solid particles by the too rapid expulsion of the volatile matter. The possibility of loss from this source is mentioned in the report of the committee of the American Chemical Society, but the results of their experiments are negative. (2) A different breaking down of the hydrocarbon compounds when expelled under different conditions and in...
Seite 50 - ... constructions, such as sprinkler equipments, automatic fire doors, wire glass, etc. They recommended that prompt measures be taken to relieve the hazardous conditions in narrow streets by widening the streets or enforcing adequate window protection, or both, and advised that automatic sprinkler equipments be required in all buildings which by reason of their size, construction, or occupancy, singly or combined, might act as conflagration breeders. The potential hazard was considered very severe,...
Seite 140 - In fact, San Francisco has violated all underwriting traditions and precedent by not burning up. That it has not done so is largely due to the vigilance of the fire department, which cannot be relied upon indefinitely to stave off the inevitable.
