visibility improved on tlie Grand Banks along track E and ice reports 

 were received from two vessels in that area reporting 13 separate bergs. 



On April 24 the fog lifted at 6 a. m. and it was generally clear over 

 the entire ice-patrol area. The Mendota searched from latitude 

 43°00' N., to the northward in the cold current between the 100- 

 and 1,000-fathom curve just east of the Grand Banks. At 12:50 

 p. m. we located a berg aground in 34 fathoms of water in latitude 

 44°23' N., longitude 49°10' W. This berg was about 45 feet high, 

 225 feet long, and 100 feet wide. It was entirely water washed and 

 several old water lines were visible, giving evidence that it was an 

 old berg that did not complete its southward journey last year. From 

 this berg the ice-patrol vessel continued its search to the northward 

 just east of the 50-fathom curve as far north as 45°30' N. Ice was 

 located in the following positions: Two bergs 45°12' N., 48°55' W.; 

 berg 45°16' N., 48°55' W.; berg 45°30' N., 48°50' W. These bergs 

 were also aground and gave evidence of being last year's bergs. Then 

 the Mendota ran east for 12 miles and stopped and drifted on account 

 of darkness. During the 25th and 26th fog prevented all scouting. 



On the 27th the ice-patrol vessel scouted with good visibility to the 

 northward from latitude 45°00' N., to latitude 45°50' N., in longitude 

 46°40' W., and then westward to the 50-fathom curve. A berg was 

 located in 45°45' N., 48° 31' W., in 61 fathoms of water. This was 

 a large solid berg about 300 feet long, 200 feet wide, and 100 feet 

 high at the highest peak. From this berg the Mendota searched to 

 the south-southeastward until dark. At daylight the following 

 morning we contacted the General Greene and received a current chart 

 of the critical ice area which the oceanographer on the General Greene 

 had just completed. Then we scouted to the southward east of the 

 Grand Banks on courses parallel to and 24 miles east of those we 

 steered on our northward search on the 24th. Good visibility pre- 

 vailed until 3:20 p. m., when dense fog set in. 



During the night of the 28th the Mendota ran to the westward 

 toward the relieving point. The Pontchartrain was met at 8 a. m. 

 April 29, in latitude 42°30' N., longitude 52°45' W. Lt. R. M. Hoyle 

 and ice observation party were transferred to the Pontchartrain, and 

 the Mendota was relieved as ice-patrol vessel. Then we proceeded 

 to Halifax, Nova Scotia. 



The limits of the ice during the period of this cruise were unusually 

 far on the Grand Banks in shoal water. In fact bergs were numerous 

 on the Grand Banks from the eastern edge as far south as latitude 

 44°00' N., and westward to longitude 53°00' W. The southernmost 

 ice was a berg reported on the 13th in 43°57' N., 48°47' W. This 

 berg could not be located on the 24th when the fog cleared, affording 

 the ice-patrol vessel the first opportunity to scout the area since arriv- 

 ing in the ice regions on the 16th. This berg and the berg sighted by
