32 



from 10 stations; 31 ships were furnished with special advice on 

 request. 



At the end of the cruise on June 20 it was estimated that about 

 27 bergs remained south of the forty-eighth parallel. Fully 22 of 

 these were grounded on, or were very near to the Newfoundland 

 coast and would never get anywhere near the United States-Europe 

 tracks. The three bergs reported and the one sighted south of the 

 Tail all undoubtedly melted before the cruise ended. 



On June 20 it could be stated fairly definitely that there was no ice 

 nearer the B tracks than 250 miles. To reach these tracks it would 

 have to follow the Labrador current down along the eastern edge of 

 the Banks and past the TaU, a distance of over 350 miles. At this 

 season the time that would be consumed in traveling this distance 

 should suffice to melt any ordinary berg that might hereafter have a 

 tendency to drift south because of its favorable location in the axis 

 of the Labrador Stream. The ice menace to the B tracks was believed 

 definitely over for the season of 1928. The above conclusion was 

 arrived at in a conference held on board the Modoc as soon as the 

 Mojave was met on the morning of June 20. 



THE SEVENTH CRUISE, " MOJAVE," JUNE 20 TO 23, 1928 



The Mojave took over the oceanographic party and the ice-patrol 

 duty at about 11 a. m. on June 20 in 45° 09' N., 51° 40' W. Nearly 

 all the oceanographic gear on the Modoc was received at this time also, 

 for further transfer to the Marion for use on a proposed cruise to 

 Greenland waters. 



Just after the relief was efl'ected the commander, international ice 

 patrol, sent a message to Coast Guard headquarters from the Modoc 

 recommending the discontinuance of the 1928 patrol. Pending 

 receipt of orders resulting from this message the Mojave undertook 

 to search again along the eastern edge of the Grand Banks from 46° 

 45' N. to 43° N. 



By running at' 100 revolutions per minute during all times of good 

 visibility the second search within a week of this area was finished 

 before dark on June 22. The Hmiting longitudes were 47° 00' W. 

 and 51° 30' W. Again no ice was seen, but a band of water about 

 30 miles wide with surface temperatures from 39° to 41° F. was 

 encountered until the patrol vessel had passed to the westward of the 

 fifty-first meridian. Moderate weather prevailed and the only thing 

 that hampered searching was the usual fog that was occasionally 

 experienced in banks and patches. 



At 6 p. m. on the 22d orders were received by radio from the Modoc 

 at Halifax for the Mojave to discontinue the ice patrol and to return 

 to Boston. Favored by easterly breezes at first, but hampered greatly
