In the first district, between Pedro Miguel Locks and the sea, were removed 5,364,816 cubic yards, of which 3,329,072 cubic were taken from within the canal prism and the balance was iliary work. Of the amount removed from within the canal p 1,186,432 cubic yards were of rock. Of the rock excavated, 14 cubic yards were drilled and blasted by the drill barge Terede 60,832 cubic yards were broken by the rock breaker Vulcan. remainder includes rock which had been drilled by well drills blasted in previous years and material which could be handled b dredges without mining. The average cost of prism excavation $0.2578 per cubic yard. Active operations began in Culebra Cu October 23, 1913, and continued throughout the year; a tota 3,432,363 cubic yards were removed, of which 919,655 cubic y were of earth and the balance rock. The average cost was $0. per cubic yard. Of this amount, 865,015 cubic yards of earth 1,557,360 cubic yards of rock were removed from Cucaracha slide an average cost of $0.4730 per cubic yard. Pipe-line dredges, with assistance of a relay, pumped over the west bank of the canal into Rio Grande Valley 684,514 cubic yards of earth and 77,880 cr yards of rock, at an average cost of $0.2773 per cubic yard. Cu racha slide has been very active since dredging operations start the daily movement averaging about 23 feet. On June 30, 1914, total area of the slide was 60.4 acres, 44.6 acres active and 15.8 ac without motion. Dredging was done during four months of the ye in Miraflores Lake, removing 159,817 cubic yards of earth from t panal prism, at an average cost of $0.3179 per cubic yard.

In the second district 6,544,192 cubic yards were removed duri the year, of which 3,692,576 cubic yards were removed from with the canal prism, 371,630 cubic yards from old French dump in Lim Ray, and the balance was auxiliary work. The average cost of pris and French dump dredging was $0.1717 per cubic yard. Of tl qm omt removed from the canal prism, 158.994 cubic yards were

housand cubic yards were placed in the fill for the substation and 204411 cubic yards were placed in fills for bridge foundations, coal basins, and yards at the coaling station.

At the Pacific terminals the dredges removed 1,919,003 cubic yards of earth and 7,964 cubic yards of rock, of which 1,831,711 cubic yards dearth were handled by pipe-line dredges and relays and placed in fills for reclaiming swamp land. The average cost of this work was $11655 per cubic yard.

A considerable amount of miscellaneous dredging was also done, making the total removed by the entire dredging fleet, including yardage of sand and gravel reclaimed, 15,341,371 cubic yards. The Set consisted of the seagoing suction dredges Caribbean and Culebra, the seagoing ladder dredge Corozal, the French ladder dredges Badger, No. 1, No. 5, Gopher, Marmot, and Mole (the last abandoned

worn out on September 20, 1913), the 5-yard dipper dredges Cardenas, Chagres, and Mindi, the 15-yard dipper dredges Gamboa and Paraiso, and the pipe-line suction dredges No. 4, No. 82, No. 83, Ta. 85, No. 86, and the Sandpiper. In connection with these dredges dere were employed 12 tugs, 19 launches, 9 clapets, and 24 dump

As noted in the previous annual report, a contract was made with e Bucyrus Co. for the construction of two 15-yard dipper dredges and their delivery at tidewater in the United States. The first was be ready for towing to the Isthmus on December 1, 1913, and the rond on January 1, 1914. The first dredge was accepted at Port Rahmond, N. Y., on February 16, reached the Isthmus on March

and was placed in operation on April 4, 1914. The second dredge was accepted at Port Richmond on April 13, reached the Isthmus May 22, and went into commission at Cucaracha slide on June 1914. Due to a failure of the buckets, which were not suffintly strong to do the work, an additional delay was caused. The are to meet the stipulated dates of delivery resulted in very serily handicapping the work at Cucaracha slide and delayed securchannel sufficiently deep and wide to permit the canal to be zlized for the passage of commerce before the close of the year. The sum of $2,000 was authorized to be expended in the construcSon of temporary dikes on the west side of the channel where it is through at the head of Limon Bay, to determine the effect upon erosion that was occurring, due to the waves created by the trade winds. The results were so satisfactory that it has been decided to Dake these dikes permanent.

MECHANICAL DIVISION.

The mechanical division was in charge of Mr. A. L. Rc until July 19, 1913, when he resigned from the service. Subs to that date and until March 6, 1914, Lieut. Col. T. C. D United States Army, performed the general duties relating ganization and personnel, while the operation of the shop under the supervision of Mr. John J. Eason as assistant su tendent. On January 26, 1914, Mr. D. C. Nutting, United Navy, reporting for duty, was assigned as superintendent and over all the duties performed by Col. Dickson in connection this division.

The establishments under operation by the division consist the Balboa shops (including roundhouse and car shops), the tobal shops and dry dock, Paraiso shops, Cristobal roundhous small hoisting establishments at Gatun, Empire, and Paraiso the car inspecting establishments at Cristobal and Balboa.

The Cristobal shops and dry dock have been charged wit repairs to floating equipment; as this dock was the only one at able when a dry dock was necessary, it was in practically continen use throughout the year. For the purpose of docking the five marines which are on duty on the Isthmus and for docking Ceret the upper lock of the east flight at Gatun was used. Paraiso shops were reestablished on October 22, 1913, to take of repair work on the dredging equipment operating in Cule Cut The hostling of four engines operating in this vicinity turned over to these shops on May 25, 1914, and is performed ur the foreman machinist. The Cristobal roundhouse was turned to the mechanical division on April 1, 1914, and all hostling at mirth end of the canal was concentrated there. The establishm in addition to the roundhouse, comprises a small boiler plant s twie wit compressors with a combined capacity of about 2,000 f por minuto. The plant supplies air for hostling purposes and a For work on the new piers of the Panama Railroad. A small hostli plant was published at Empire, in the shops vacated, March With the potablishment of the electrical division on April 1, 19. the electrical plants at Empire, Miraflores, Gatun, and Balboa, pi.. lily (gorated by the mechanical division, were turned over Hot dick on and, as these plants contained air compressors, the a kampaisende were likewise turned over to the electrical divisio This did shipways shops at the Pacific entrance, formerly occupie by this deachding division, were turned over to the mechanical div pin on October 5, 1914, and so continued until they were torn dow in March and April The machine shops and engine house at Gatu were operated for work in connection with the installation of lock ma

chinery and caring for locomotives engaged in that vicinity. They were abandoned April 1, 1914, and the work transferred to Balboa and Cristobal. The Pedro Miguel engine house was abandoned on September 15, 1913, and the greater portion of the equipment moved to the Gold Hill engine house and the buildings turned over to the quartermaster's department and torn down. An engine house was established at Gold Hill in September, 1913, to care for the equipment employed in dry excavation north of Gold Hill. The engine bouse continued in operation until completion of the excavation work and was discontinued on March 31, 1914. The air-compressor plant at Rio Grande, which had been in operation since 1905, was shut down October 15, 1913, and such compressed air as was required in the Estrict previously supplied by Rio Grande was furnished by the ant at Empire. The Cristobal car shops were in operation until March 7, 1914, when they were abandoned and all car work contrated at the Balboa shops. When the Balboa roundhouse was put into service on April 1, 1914, the Panama roundhouse of the Panama Railroad was placed out of use.

Throughout the year, while the shops were in operation, two shifts vere regularly worked at Gorgona, Empire, Paraiso, and Balboa. la addition to the double shift, emergencies continually arose which ecessitated large amounts of overtime work, in order that equipzent might be kept in condition for use and to prevent delay in the Fork of other divisions.

For further details, as well as a statement showing the amount of rk done during the year by the various shops, attention is invited to Appendix D.

DIVISION OF TERMINALS.

The division of terminal construction was organized on April 1, 34, under Mr. H. H. Rousseau, United States Navy, as engineer of arainal construction. The division embraces the forces of the farmer second division, chief engineer's office engaged in the design, pection and construction of the dry docks, shops, coal and fueli plants, floating cranes, docks and other terminal facilities; contraction transportation by rail; the road, street and sewer work der the landscape architect; and the breakwater construction at e Atlantic terminal.

Dry docks.-The general description and principal dimensions of Dry Docks No. 1 and No. 2, at Balboa, were given in the previous al report. On account of the condition of funds, it was decided to defer the construction of Dry Dock No. 2, but such of the dock ture as serves as an entrance pier for Dry Dock No. 1, and as permit the future completion of Dry Dock No. 2 in the dry Tout especial increase in cost will be built now. The cofferdam,

which was begun on April 1, 1913, to protect the entrance of Dock No. 1, Dry Dock No. 2, the entrance basin, and coal-pocke cavations, was completed by placing 103,116 cubic yards of mat Difficulty was experienced through a portion of the double-1 trestle giving way and moving outward after dumping from it commenced, but this was overcome by reinforcing the outer to dumping material from barges and the cofferdam was compl The leakage through it is relatively small and can be controlle pumps. In excavating for Dry Dock No. 1 and Dry Dock No. 2 coal pockets and entrance basin, the old Balboa machine forced the work to be confined to the center and south sides 1 November, when they were demolished and the last obstacle to cavation was removed. The total amount taken out from the sit Dry Dock No. 1 during the year was 358,282 cubic yards, 48,838 c yards of which were classified as earth and the balance as rock, n ing a total of 466,975 cubic yards excavated from this area up to close of the year. The division cost for the year was $1.0250 cubic yard, and the average division cost of the total was $0.9946 cubic yard. From the site of Dry Dock No. 2, which is located north of the entrance of Dry Dock No. 1, there were removed dur the year 41,548 cubic yards of earth and 52,129 cubic yards of r at an average division cost of $0.8129 per cubic yard. Steam-sho operations deepened the excavation from -13.5 to the final gr for the entire area of the approach basin inside of the cofferdam, ‹ a total of 351.333 cubic yards were removed at a division cost $1.0230 per cubic yard. The area required for the storage of c and for the travel of unloading towers measures 800 feet in leng and about 400 feet in width, measured from the outer edge of 1 quay wall. The total amount of excavation during the year w 166,104 cubic yards, 79.837 cubic yards of which were earth and t balance rock. The average division cost was $0.7984 per cubic ya The material excavated from the site of the dry docks, entrance bas and coal pocket was removed by means of steam shovels, three which were worked 8 hours a day until February, 1914, when on t 5th of that month the shovels were placed on a 12-hour basis an another shovel added. These shovels worked on split shifts, hours a day, continuously to the end of the year: one shovel was r moved in June. The contract entered into October 12, 1912, for or pair of steel miter-gate leaves and fixed irons was completed durir the fiscal year, and the material is stored on the Isthmus awaitin erection. The moving machines for operating the leaves, togethe with motors, controls, and covers, are also delivered.

Balboa coaling station.-Upon completion of the excavation fo the coaling plant, work was begun on masonry for the crane runwa supports, which extend east and west through the center of th
