GAS COMPANIES AND ELECTRIC LIGHTING.
THE various gas companies of the United States are considering very carefully the question of combining electric lighting with their gas plant. Many of the companies have already accepted the situation and have now become earnest advocates of a combination. We have been
informed that the following gas companies that have adopted the American system of electric lighting:
The majority of the above companies find the electric light working so satisfactorily, and so much more profitable in connection with gas than at first anticipated, that they are now contemplating increasing their arc light apparatus. _
THE well of Joseph is a fine example of the skill and boldness of design of the well-sinker. Although called after Joseph by the Arabs, it is by no means of so ancient a date as the name would imply, for the well was probably sunk about 700 or 800 years ago, but by whom is a disputed point; some attributing it to a vizier of the name of Joseph, others to Saladin, the intrepid defender of his country, whose name was Yussef (Joseph). The well consists of two shafts, one above the other but not in the same vertical line. The upper shaft is an oblong excavation 24 feet by iS and 165 feet deep, descending into a large and capacious chamber, in the door of which is constructed a basin or reservoir for conutfrning water that is raised from the lower shaft. In this chamber a lower shaft is sunk in which is an excavation of 15 feet by 9 feet and 130 feet deep. Round the upper shaft a spiral passage 6 feet 4 inches wide, and 7 feet 2 inches high is cut, separated from the well by a partition wall of solid rock only six inches in thickness, through which loopholes are pierced for lighting the passage. This passage is made use of by parties who draw water, and also for the descent of mules or other animals that are employed in the chamber below, to give motion to a system of chain pots by which the water is raised from the lower shaft and poured into the basin in the chamber. There is also a spiral passage around the lower shaft, but it is not enclosed from the well, as in the case of the passage round the upper shaft. The water of this well is procured from a bed of gravel, after penetrating the strata to the depth before mentioned.
