headquarters of plan to search two days for derelict and then re- 

 turn to Boston. Indications of drift 50° true 0.8 mile per hour. 

 Perhaps one-half of this was wind drift. 



SUMMARY 



Forty-six per cent of fog was experienced in this period, which is 

 slightly below the normal of about 55 per cent, as given on Pilot 

 Chart. Only 3 hours of gale and 14 hours of strong breezes were 

 ■experienced, which is marked^ below the normal. The disappear- 

 ance as a menace of the single iceberg on June 23 in latitvide 46° 58', 

 longitude 51° 18', indicates continuance of extraordinary absence 

 of ice. 



Broadcasts and reports to Hydrographic Office and Weather 

 Bureau were carried out, as required by instructions. The patrol 

 received 457 surface-water temperature reports, 3 ice reports, and 6 

 wreck and obstruction reports. 



The derelict schooner bottom up being sought at close of ice patrol 

 and last reported June 12, latitude 43° 00', longitude 54° 45', is 

 manifestly the same schooner that was reported May 11, in latitude 

 44° 39', longitude 55° 08', and was sought by patrol vessel Ma}' 

 20, 21, and 22. 



This derelict had drifted, in 32 days, 101 miles 170° true. This 

 being contrary to the expected drift northward is a further indica- 

 tion of the slacking this season of the usual northwest current 

 around the Tail of the Bank.
