The only extra increase would be for help in these departments which would be governed by the amount of work required.

Mr. Sutton has not included the Boyes Monorail in his report because he was asked to make an estimate for a single mile of Roadtown. For this length the auto service is the more economical. Mr. Sutton, however, finds no fault with the Monorail, as is seen from the following letter: _Mr. Edgar Chambless, New York City._ DEAR SIR: In reference to the adoption of the Boyes Monorail system for Roadtown would say that I have carefully examined the drawings and general outline of the scheme designed by Mr. Boyes and believe it to be well adapted as a means of rapid and noiseless transportation, and further believe that the operating expenses of this system and the cost of construction will be extremely reasonable. The design of the system from a mechanical and electrical standpoint is entirely practical. Very truly yours, FRANK L. SUTTON. The total cost for building and operating the Boyes monorail system between New York and Philadelphia or for ninety miles is estimated by Mr. Boyes as follows: ESTIMATED COST OF BUILDING AND OPERATING ROADTOWN TRANSPORTATION. As submitted by Wm. H. Boyes using the Boyes Monorail system.
