latitude 44° N., during the period of fog. A berg was located in 

 latitude 43°19' N., longitude 49°25' W., and two large growlers in 

 latitude 43°00' N., longitude 49°16' W. As the two growlers were the 

 southernmost known ice, the Tahoe stopped to drift with these and 

 observe their movement. The next, April 18, the Tahoe scouted 

 northward with full visibility to latitude 43°50' N., but no new ice 

 was sighted. The berg of the previous day had drifted 30 miles to 

 latitude 42°55' N., longitude 49°49' W. One of the two growlers had 

 disappeared, but the other was located in latitude 42°42' N., longi- 

 tude 49°43' W. At the end of the day's search the Tahoe headed 

 westward for the relieving point. 



The Pontchartrain was met at 0528, April 19, 1938, in latitude 

 43°33' N., longitude 53°50' W. A boat was lowered and Lt. G. Van A. 

 Graves, ice-observation officer, and the observer's party were trans- 

 ferred to the Pontchartrain and at 1230 the Pontchartrain relieved the 

 Tahoe as Ice Patrol vessel. The Tahoe set course for Halifax, Nova 

 Scotia, arriving there at 1415 on April 21, 1938. 



Medical advice by radio was given the Steamship Endicott, which 

 had a patient suffering from acute infection of elbow glands. Treat- 

 ment was prescribed on April 11 and on April 13 the patient was 

 reported as improving nicely. Also one Henri Lechevestrier, who was 

 taken aboard from the French barkentine Capitaine Guynemer for 

 treatment for mild pneumonia, is doing nicely and will be returned to 

 his vessel when able to work.
