...York, and of the various pleasant excursions which could be made in that vicinity. The gazette states that although "the streets of the ancient or lower part; at the south end of the island, were irregular, many of them are narrow and crooked, with little adaptation to the ground, or to the convenience or elegance of the city, the northern part was laid out in much better taste. Many of these streets were very spacious, ran in right lines, and were intersepted by others at right angles. And the quays and wharves were far extended into the original waters that...
...time ago, when the City requested the proposed exchange. Harvard consented, and the matter was referred to the Council which submitted to Nelligan the legal aspects of the question. There is some doubt as to whether Harvard will be able to erect buildings on Holmes Place, which is common ground, originally part of the City Common...
Irregularities in the earth, such as masses of rock of lower or higher density than the surrounding material, or of higher or lower electrical conductivity influence the natural physical fields of the earth or artificial physical fields that can be found on the ground in question. The normal fields can be calculated accurately, and by measuring the departures from the normal, evidence is secured that is of possible service in estimating the properties of the mass concealed in the earth that is responsible for the departures...
...body of sulphide ore, for example, generally has higher electrical conductivity than the surrounding rock. If an electric current is passed through the ground, the flow of electricity will tend to concentrate in the material which offers least resistance to its passage, and valuable evidence concerning the relative conductivity of the rocks that comprise the area can be gained by observing with suitable devices the distribution of current. A convergence of flow lines into a good conductor can be readily detected, and even the effects of better conducting material at considerable depth can often be estimated with a fair degree...
...amount of rotation of a light beam appropriately weighted and suspended on a thin platinum wire. Ore bodies themselves are rarely large enough to cause detectable variations in gravity, but large features such as heavier rock in cores of folds, dome-shaped masses of salt, or bleached cavernous ground can often be recognized by the anomalies caused by them in the gravitational field, and critical evidence bearing on the occurence of oil or ore bodies, may be secured for the use of the geologists...
