The scientific program was limited this year, as in the last 7 years, 

 almost entirely to oceanographical investigations. These studies and 

 observations may be divided into two phases. One, the work during 

 the ice patrol season, which is of immediate and practical value to the 

 patrol vessel, and two, the continuing, long term program of research 

 carried on during the post-season cruises and the interim periods be- 

 tween seasons. The first phase consists of the construction of surface 

 current charts covering approximately the area of principal activity, 

 about 50,000 square nautical miles, each month. (See fig. 1.) The 

 charts are, as can be easily understood, of inestimable value to the 

 patrol vessel showing, as they do, the direction and velocity of the 

 currents in this important area. (See figs. 34, 35, and 36.) The three 

 charts constructed this year, one in April, one in May, and one in June, 

 are thoroughly discussed and analysed elsewhere in this bulletin under 

 Oceanography (p. 71). The second phase of this program for 1937 

 consisted of a post-season cruise the purpose of which was an investiga- 

 tion of the Labrador and Atlantic Currents and their common 

 boundary from the Grand Banks eastward to longitude 40° W. The 

 results of this investigation are discussed under Oceanography 

 (p. 71) and a narrative account of the postseason cruise may be 

 found under Cruise Reports (p. 40). 



During the season the patrol ships were able to give medical assist- 

 ance and advice in the following cases: (1) February 10, S. S. Saga- 

 porack, patient suffering from badly injured eye. Advice was given. 

 by radio but no report of the patient's progress was received. (2) 

 March 18, steam trawler Imperialist, patient suffering from serious 

 infection of hand and arm. The patrol vessel took the man aboard 

 for treatment and when cured he was returned to his home in New- 

 foundland via commercial steamer. (3) April 13, S. S. West Queeche, 

 patient suffering from acute and probably infectuous disease. Advice 

 by radio was given but no report of patient's progress was received. 

 (4) April 22, steam trawler Imperialist, patient suffering from infected 

 gum or jaw following extraction. Advice was given by radio and the 

 patient was reported as greatly improved. (5) April 28, S. S. Srane- 

 holm, patient suffering from suppuration in upper jaw and possible 

 blood poisoning to the brain. Advice was given by radio and arrange- 

 ments made to transfer patient to S. S. Scanmail, bound New York. 

 Transfer was effected 7 hours and 30 minutes later, (6) June 3, 

 trawler Cormorant, patient brought aboard and transferred to Halifax 

 for hospitalization. More com.plete accounts of these cases will be 

 found under cruise reports (p. 25). It might be mentioned here that
