There will be five departments for the operation of the canal outside of the work of maintaining the civil government and sanitation. The operating department will have charge of the operation of docks and wharves at the terminals, pilotage, lockage, and the lighting of the canal. It is estimated that it will cost $400,000 a year to maintain the terminals, $150,000 a year to light the canal, and that it will require 60 pilots, at $1,800 each a year, to take ships through. During the first years of operation it is believed that a single shift can handle all the business that comes, but, as the years go by, it may require two shifts and eventually three to keep the work going. The engineering department will require about 500 men and will have charge of all the construction and repair work pertaining to the canal property, and of all excavation and dredging in the canal. It will cost approximately a million dollars a year to maintain this department, of which three-fourths will be required for the operation of the dredges and other equipment for keeping the canal open. The quartermaster's department will have charge of the construction, repair, and maintenance of all buildings, roads, and municipal improvements in the Zone settlements and of the receipt, care, and issue of all property and material. This department will require nearly a thousand men and the total expense will be in the neighborhood of $600,000. The electrical and mechanical department will have charge of the mechanical and electrical apparatus belonging to the canal, and of the permanent works at its two ends. The accounting department will require some 60 men with annual salaries amounting to approximately a hundred thousand dollars. It is estimated that the cost of materials for the operation of the canal will range around three-fourths of a million dollars a year. The force which will be maintained on the Isthmus, with their families, will make a Canal Zone population of approximately 5,000. These, in addition to the eight or nine thousand troops and marines which will be quartered there, will bring the total population up to about thirteen or fourteen thousand. Of these perhaps three-fourths will be along the southern 10-mile section of the canal. But, in spite of the greater population at the Pacific side, the Atlantic end will probably not lack for attraction. It is likely that Gatun Lake will be stocked with a supply of fresh-water fish, and that shooting preserves will be established adjacent to Gatun, to be conducted in connection with the Washington Hotel at Colon. There is also some talk of constructing golf links adjacent to Gatun, which will be open alike to the employees of the canal and to the guests of the two big Government hotels--the Washington and the Tivoli.
