PROGRESS OF THE PANAMA CANAL.
The report of progress of the work on the Panama canal, so far as it regards hydraulic engineering, in cludes the following items: Surveying parties are at work in the vicinity of Colon making plans and estimates for an inner harbor, and also for the work to be done in the outer bay. At Gatun, surveying and boring at the various proposed dam sites in that neighborhood, and for a cut-off, known as the Tiger Hill line, between Gatun and Tiger Hill; at Bohio, making detailed surveys and studies and investigating the various dam sites that have been proposed in that locality; at Gamboa, making detailed borings and surveys and estimating for a dam at that point; also making a survey of the watershed of the Chagres river above Gamboa and surveys and investigations to determine the possibility of spillways into the Pacific on the one side and the Carribean on the other; also a survey and examination, with estimates, for the proposed dam at Alhajeula. An engineering force in charge of sewerage and water supply for Panama and Colon and under the direction of the engineer of sewerage and water supply is now constructing a reservoir in the valley of the upper Rio Grande, which will furnish a minimum supply of 2,000,000 gallons a day for the city of Panama; also a distributing reservoir for the city of Panama at Ancon; also making surveys, plans, and estimates for a sewerage system for the city of Colon and surveys and estimates for establishing official grades for the streets of Panama. Bids have been received for the pipes for leading water into Panama. A contract will soon be made. Bids are to be received in a few days for the material necessary to construct the sewerage system at Panama.
Water from the new purifying plant at Fort Lincoln. N. D., shows a marked improvement. Still the plant is looked upon as only a makeshift at best, and that in the long run connection with the city system, with abundance of pure water and good pressure at all times, is altogether the best solution of the water problem. Failing that, the government should go to the river and install an independent plant.
