Banks. This fog lasted until 4 a. m., April 4, when a cruise was 

 again undertaken to the northward. The vessel passed through a 

 portion of the French fishing fleet that had arrived on the Banks, 

 speaking 12 vessels, receiving their mail, rendering such medical and 

 other assistance as was necessary, and giving positions to three. 

 On the morning of April 5 a WSW. gale set in. The patrol ship 

 was hove to a short distance away from the French schooner L'Essor 

 which vessel desired her position. The gale lasted until noon April 

 6, when a cruise to the northward and eastward between latitudes 

 46° and 47° was attempted in search of ice. A SW. gale and snow 

 was encountered and the vessel again slowed down. Word having 

 being received at midnight April 7 that the Modoc had left Boston 

 for the patrol, the vessel was headed south and west to a designated 

 rendezvous in latitude 45° 00' N., longitude 55° 00' W. Shortly 

 after heading south the wind hauled more to the westward. The 

 course of the vessel was changed to meet the new condition. The 

 relief was accomphshed at 8 a. m., April 9, in latitude 44° 22' N., 

 longitude 56° 34' W. 



EESTJME 



During this cruise all the regular broadcasts and three special 

 broadcasts were transmitted; 5 vessels were instructed as to safe 

 course, 4 vessels were given special information, 14 were furnished 

 positions and 18 were given weather information. Four reports of 

 dangers to navigation were received and broadcast, and 710 water 

 temperatures were received and plotted. 



WEATHER 



(See Charts Nos. 8, 9, and 16) 



The weather experienced during the latter part of March was 

 exceptionally good with less than 50 per cent of fog. However, 

 during the first four days of April delise fog was encountered while 

 from April 5 to 8 intermittent gales from various points of the com- 

 pass liindered successful searching. 



WATER TEMPERATURES 



(See Charts Nos. 8 and 9) 



The water temperatures and profiles plotted divulged some inter- 

 esting facts. One of the most striking was the decided movement 

 to the northword of the cold wall, even in excess of 1924; another 

 was the disappearnce of the 32° line on the southern part of the 

 Banks with only a slight touch of cold water along the forty-fourth 

 parallel; a third was the prevalence of warm water where Arctic 

 water was usually found, and last the fact that the cold wall had a
