Walker, chairman of the Panama canal The engines will be of the usual vertical, inverted, direct- commission, announced in Washington last week that actual acting, fore-and-aft compound type, with cylinders 13 and 26 work on the canal would be begun after the commission has been a few weeks on the isthmus, for which it sailed on Tues- MAIN FRAME, day last. A large number of inspectors will. be employed Pe by the commission. Admiral Walker is opposed to the se- lection of these inspectors through the civil service commis- eat sion. He is a thorough believer in the civil service, but does not think it would be satisfactory on the Isthmus of Panama. anna Admiral Walker explains that the estimated cost of the canal oo made by the last commission did not include the expense of governing the canal's zone. Intense interest is being taken in the construction of the canal by prospective contractors. On the steamer on which the commission is to sail for the isthmus, practically every stateroom has been engaged by agents of contractors who want to look the ground over. Admiral Walker has advised congress that no law be enacted requiring the work to be done by contract. It is the inten- tion of the commission to continue actual work on the canal as now being carried on by the French company in order to ------ demonstrate the exact cost of such work. He explained to the interstate and foreign committee of the house of repre- GARINE REVIEW sentatives that the greatest engineering feat of the whole en- terprise would be the construction of the Bohio dam.
