treatment. Foiir hundred and fifty sea-water temperatures were 

 furnished to us by 120 steamships. 



The following oceanographical and biological stations were estab- 

 lished: (See chart "A.") 



The only icebergs reported to date were those sighted by the 

 steamship Dighy on the SE. coast of Newfoundland on February 14. 

 By February 25, 1921, two bergs had been reported in lat. 45° 56' 

 N., long. 50° 57' W., and one berg in lat. 44° 25' N., long. 50° 54' W. 

 In comparing the location of the bergs sighted in February of this 

 year vntli those sighted in February of last year, it will be noted that 

 the southernmost berg sighted in 1921 (on February 25) was 150 

 miles south of the southernmost berg sighted in February, 1922. 

 To date the season is no further advanced than it was last year, 

 when the first bergs arrived below the Tail of the Bank on April 4. 

 It is fair to assume that their progress southward this year will not 

 be in advance of that of last year. 



No field ice was observed on February 18, 19, and 20, dm^ing om* 

 cruise along the east edge of the Bank, between lats. 44° 30' N. and 

 46° 50' N., although it had been reported in that locality on Feb- 

 ruary 12, 13, and 14. 



At the intersection of the 45th parallel and 47th meridian, where 

 we expected to find "mixed water," the sea water was of a miiform 

 temperature of 50° from the surface to a depth of 250 meters. This 

 would seem to indicate that the Labrador Current had not gathered 

 its spring velocity. On the 14th light field ice in patches was reported 

 as extending across the Bank, just north of the 46th parallel. No 

 other report concerning this ice was received until the 18th, when 

 the steamship Sachem encountered an ice field in lat. 45° 45' N., long. 

 51° 50' W. As these ice fields were light and far removed from the 

 steamship lanes, no attempt was made to locate them. 



Reports to the Hydrographic Office, New York, were made from 

 the date of arrival on the Great Bank, February 19, to date of arrival 

 in the longitude of Sable Island, Februar}^ 26, inclusive.

 Ice Observation, Second Cruise, March 13 to April 1, 1922. 



The Seneca left Halifax March 13 and set course south of Sable 

 Island, as considerable field ice had been reported to the north of 

 that island. On the 14th, the barometer fell steadily from 30.21 

 to 29.49. There was a fresh SW. wind, which at the end of the day 

 veered to NW. ; the sky was partly cloudy to overcast and hazy; 

 and there was a rough sea. On the 15th, the wind increased to a
