from an average of about 40 feet per minute to 

 about 300 feet per minute with a load of about 

 V,000 lbs.; in any gear the motor can be varied 

 by the rheostat from almost nothing up to 150 

 per cent of rated speed. 



Laboratories . - As shovm in figures 4 and 5, 

 there is a laboratory in the afterpart of the 

 deckhouse and three others below deck. Athwart 

 ship the deck laboratory measures approximately 

 9 feet, its port half being 7 feet long and its 

 starboard half 10 feet. Forward on the star- 

 board side a door leads to the deck, a second 

 door to the pilothouse, and a hatch to the lab- 

 oratories below. On the starboard-deck labora- 

 tory wall, aft of the door to the deck, and on 

 most of the after wall there are racks for about 

 twenty Nansen reversing water-collecting bottles. 

 Under the Nansen bottle racks are racks for 

 various types of bottles for water samples. Along 

 the entire portside there is a laboratory bench 

 with an acidproof sink and a salt-water hand 

 pump. Under the bench are drawers and lockers. 



The below-deck laboratories (fig. 5) occupy 

 all the space to starboard of the center line 

 and between the saloon and lazaret te bulkheads. 

 These laboratories are arranged in three sec- 

 tions. The after section, which connects di- 

 rectly with the deck laboratory, has shelves for 

 storing water samples, an electric refrigerator, 

 and a small laboratory bench. The center sec- 

 tion at table height measures only about 6 ft. x 

 6 ft. , but it has convenient working benches on 

 three sides and can be darkened whenever neces- 

 sary for colorimetric and similar work requiring 

 reduced light. The forward laboratory section, 

 measuring 8 ft. x 10 ft., has a ty^jical chemical 

 laboratory bench about 6 ft. long, with a cen- 

 tral drain trough above which are shelves for 

 apparatus and reagent bottles. At the end of 



the trough is a rack for holding chemical-proof 

 buckets, into which can be discharged solutions 

 that may damage the ship's drainage system. This . 

 room also contains a sink with fresh-water taps 

 for washing glassware, lockers and shelves, and 

 another laboratory bench situated under a sec- 

 tion of the main companionway trunk where appara- 

 tus up to 6 ft. in height may be installed. All 

 the laboratories are equipped with an adequate 

 number of 115-volt , B.C. electric outlets. On 

 each side of the bench in the forward laboratory 

 there are two folding seats surfaced with mason-

 off La Jolla in May, 1939. 



Since the above description was prepared, the 

 following changes have been made : 



Construction and Design . - In the fall of 

 1939 the bowsprit was cut off and the forward 

 rail was built up to approximately 18 inches 

 higher at the stem and tapering back to 6 1/2 

 inches higher at the forerigging. 



Rigging. - In the fall of 1939 the foregaff 

 was removed and the foresail was cut to a leg-of- 

 mutton sail. 



Deck Fittings . - In July, 1941 the skylight 

 aft of the dredging winch was replaced by a 

 solid trunk. In the forward third of the trunk 

 where the batteries are stowed, small ventilators 

 were placed on top of the trunk. In the after 

 two-thirds of the trunk were placed ventilators 

 for the engine room and saloon. The skylights 

 over the galley were replaced by solid trunks 

 with portholes. 



Machinery . - In August, 1940 the Uinton diesel 

 engine was replaced by a 170-HP Gray marine 

 diesel engine, the exhaust of which discharges 

 through a short straight pipe passing through the 

 engine-room trunk. Engine-room controls were in- 

 stalled in the wheelhouse.
