and 266. Many fulmars were noted, both near the bergs and out 

 of sight of them. 



April 17: Stood to the westward, along the western radial of 

 oceanographic stations, occupying stations 267 and 268. At 2 

 p. m., met the Tampa, in lat. 43° 02', long. 54° 27'. The oceanog- 

 raphic observer was transferred from the Modoc to the Tampa and the 

 latter vessel took over the ice patrol duty, the Modoc proceeding 

 to Halifax. 



ICE INFORMATION AND WARNINGS. 



In this report of work performed by the patrol vessel, there is 

 included each day a list of vessels to whom ice information and ice 

 warnings have been sent. The details of some of these cases may 

 prove interesting and are given below. 



Steamship Liljevalch: The steamer Liljevalch at noon, April 5, 

 radioed the patrol that she was stopped in lat. 49° N., long. 49° W., 

 being held fast by a high and heavy ice field that extended as far 

 as the eye could see. She was on the Cape Race steamer track and 

 asked if it would be possible to attempt further passage past Cape 

 Race. The patrol immediately advised the master that there was 

 httle likelihood of making such a passage and sent him the latest 

 ice information, recommending the follomng route, which would 

 not only guarantee safety from field ice and menacing bergs but 

 would carry him out of the fog into clear weather: ''The best practi- 

 cal route for you is from your present position to 47° N., 45° W., 

 thence to 45° N., 44° W., thence to 42° N., 47° W., then steer west 

 until after crossing 52d meridian. Keep patrol advised of your 

 movements." Nothing was heard from her until noon of the 6th, 

 when she sent her position, reported two bergs, stated she was follow- 

 ing our previous instructions, and asked for new developments. 

 The patrol replied that it was searching northeastward along the 

 edge of the Gulf Stream, stating that fog was over the cold water, 

 and adding "Advise you steer shortest course to warm water and 

 clear weather. That position for you is 45° N., 44° W. Keep in 

 touch with us." The Liljevalch proceeded cautiously through the 

 fog and low visibility under the directions as given. April 7 she 

 reported passing close to two bergs at 2.30 p. m. As she approached 

 the warm Gulf Stream the fog became thinner, and at 7.30 p. m., 

 April 8, she had reached lat. 45° N., long 44° W., and was in clear 

 weather, comparatively safe from bergs. 



Steamship Lulea: At 5.20 p. m., April 6, the Lulea reported her 

 position in lat. 46° 47' N., long. 42° 07' W., standing 209° true. She 

 was in fog and had slowed to 3 knots. It was immediately observed 

 that she was approaching the berg and growlers reported on the 

 5th in lat. 46° 02' N., long. 43° 19' W., therefore the patrol sent
