COAST GUARD CUTTER "MODOC, " COMMANDER B. M. CHfSW ELL, 

 ICE PATROL, SECOND CRUISE, MAY 2-17, 1923. 



The Modoc sailed from Halifax at 1.15 p. m., April 30, to relieve 

 the TamjM. The weather was storm}^ at the time, the wind varying 

 from fresh S. wind to moderate SW. gale, with thick, driving rain. 

 From the time of departure until contact with the Tampa, either 

 heavy, driving rain or dense fog prevailed. Without the aid of the 

 radio compass it would have been difficult, if not impossible, to have 

 located that vessel. At 5.20 p. m., May 2, the Tampa was relieved 

 of the ice patrol duty, in lat. 42° 56', long. 55° 22', and directed to 

 proceed to Halifax, the oceanographic observer being transferred 

 from the Tampa to the Modoc, after which the Modoc occupied 

 oceanographic station 291, at the point where the relief was effected. 

 At 7.40 p. m. steamed to the eastward. The dense fog cleared a,t 

 11 p. m. 



May 3: Moderate SSE. to SE. wind, with moderate southerly 

 swell. At 3.30 a. m. dense fog set in and lasted until 8 a. m., when 

 the fog cleared and cloudy weather, with very good visibility, pre- 

 vailed during tlie remainder of the day. Oceanographic stations 

 292, 293, 294, and 295 were occupied. At 9.20 G. M. T. a large, low, 

 irregidarly shaped, hummocky berg was located, grounded in 54 

 fathoms, on the west side of the Tail of the Bank, in lat. 43° SS'' 

 long. 51° 51'. During the greater part of the da}^ the vessel was in 

 the Labrador Current to the westward of the Grand Banks and 

 experienced a noticeable set to the northward and westward. At 

 10.50 p. m. the Modoc was anchored, to hold her position during 

 the night. 



Special ice information was given to the steamships Strassa, 

 Montrose, Cahotia, Domira, Pennsylvania, and Catinat, several of 

 which were bound to St. Lawrence River ports. They were advised 

 that the river was not yet open to navigation. Scattering fulmars 

 and dovekies were noted and many were observed flying about the 

 berg sighted. 



May 4: Moderate to fresh SE. to ESE. winds, with falling barome- 

 ter, and partly clear to overcast weather, with light rain and moderate
