position with a pnssongor ship speeding; eastward at IG knots and 

 night falhng: "The berg carried on ice broadcast in 42° 50' N., 

 50° 00' W., was hist seen evening of 14th. It was drifting 250° 

 true, rate 1 knot per hour." It was feared the Montrose might not 

 have the hitest and most complete information regarding this berg, 

 which, on the chart, hiid in her path. This is an example of the 

 duty that falls to the ice patrol, in which no erroi-s must be made, 

 in view of the life and property at stake. 



SUMMARY, 



During the patrol the weather has been unusually good for this 

 season oi the year, and the vessel has been quite active, cruising 

 under forced draft whenever visibility and the condition of the sea 

 justified it. During the tirst few days we scouted along the western 

 and northern edge of the Gulf Stream to lat. 45°, long. 43°, finding 

 clear weather over the warm water of the Stream and dense fog for 

 the most part over the cold water. This area, which abounded in 

 ice earlier in the season, was found to be clearing up. Later, we 

 investiirated conditions over the colder water and around the Tail 

 of the Bank, and occupied oceanographic stations along the eastern, 

 southern, southwestern, and western radials. Ice warnings were 

 broadcast Uvico daily, with an effective radius of approximately 

 500 miles. A daily ice report was sent to the Hydrographic Office, 

 Washington, and also to the wireless officer, Dockyards, Halifax, 

 from the 3d to the 10th. and to the Agent of ^larme. Halifax, there- 

 after. A daily weather report was sent to the Observer, ^Yashington. 

 The patrol was furnished with 1,007 sea-water temperatures from 

 ISO difTerent vessels. This hearty cooperation was most encouraging 

 to the oceanographic observer and enabled him to keep well informed 

 on currents over large areas as indicated by temperatures. Special 

 ice information was sent to 35 vessels and ice information was received 

 from 20 vessels. 



COAST GUARD CUTTER "TAMPA." LIEUT. COMMANDER W. J. 

 WHEELER, ICE PATROL. SECOND CRUISE, APRIL 17 TO M.\Y 2. 1923. 



The Tampa sailed from Halifax at 5.10 p. m.. April 15, and pro- 

 ceeded by the route south of Sable Island to the relief of the Modoc 

 on ice patrol, and met the Modoc in lat. 43° 03', long. 54° 28', at 2.40 

 p. m.. April 17. when she assumed the duties of the patrol. Gentle 

 to light southwesterly winds were experienced until noon of the 

 10th. when a fresh SE. breeze, which later hauled to W.. prevailed. 

 A strong to moderate NW. wind was experienced on the 17th. In- 

 stead of the SW. current, which is usually encountered in the vicinity 

 of Sable Island, accurate observations showed we had experienced a 

 northerly set of approximately 6 miles since departing from Halifax.
