 ICE PATROL, FIRST CRUISE, APRIL 5 TO APRIL 19, 1924 



The Tampa having inaugurated the ice patrol season, sailing from 

 Boston, March 18, 1924, the Modoc left 15 days later from the same 

 port at 10.05 a. m., April 2, 1924. Contact was made with the Tam/pa 

 in 42° 30' north latitude, 52° 46' west longitude, at 4.30 p. m., April 

 5. Lieut. E. H. Smith, observer, and Yeoman K. W. Lewis, his as- 

 sistant, transferred from Tampa to Modoc. Mail for Tampa was 

 delivered and, having relieved her of patrol duty, the Modoc at 7.05 

 p. m. stood slowly to the eastward to begin scouting for ice at day- 

 break and to relocate the berg last seen by the Tampa in 42° 35' north 

 latitude, 50° '26' west longitude, at 6 a. m. of the 5th. Weather for 

 the run out from Boston was characterized by a rapidly rising ba- 

 rometer, with westerly gale diminishing. In Boston at 4 a. m. of the 

 2d barometer was 29.25 with NE. gale and heavy snowfall. xVt the 

 time of our departure snow had ceased ; barometer was 29.50 ; wind 

 Avas west, blowing moderate gale force, with heavy banked clouds. 

 By noon of the 3d barometer was 29.95, wind force 5, Beaufort scale, 

 and partly clear; noon of the 4th, barometer 30.19, wind NNE., 

 force 3: and noon of the 5th, barometer 30.35, wind NE., force 2; 

 cloudy. 



Having run 60 miles east from the point where the Tampa was 

 relieved, a rectangular search was started at daj^break of the 6th, 

 with excellent visibility, lookout aloft. At 9 a. m. the berg last 

 seen by the Tampa on the 5th was sighted 13 miles distant. Its 

 location at noon, as determined by observation of the sun, was 42° 

 19' North latitude, 50° 39' West longitude, having drifted 226°
