time and a breeze sprang up from the northeast. The barometer 

 continued to fall until noon the 2d, when it recorded what proved to 

 be the minimum for the entire patrol (28.90; see weather diagram for 

 April), and the depression must have passed about over our position 

 south of Newfoundland. The winds with the passing of the center 

 almost immediately shifted to northwest and increased that night 

 to gale force. While we were still within the effects of the storm 

 described above, a region of new depression was observed over the 

 lower Mississippi River Valley. The path followed by this dis- 

 turbance from April 2 to 7 is shown as track D, Figure 5. This 

 center traveled along a path located a little farther to the northward 

 than that of its predecessor. It followed a straight line more or less

up the St. Lawrence Valley until it arrived at the upper reaches of the 

 gulf when it curved off to the right keeping over the water as much as 

 possible, and slowly crossed southern Newfoundland on the 5th, 

 6th, and 7th. It is important to note that this cyclone, similar to 

 several others which have been observed, deepened and intensified 

 as it proceeded up the St. Lawrence River and Gulf. It deepened 

 from a reported pressure in Mississippi of 29.76 to a minimum of 

 29.28 at Port aux Basque, Newfoundland, and it was at this point 

 approximately 450 miles from the patrol ship that the first effects 

 of the disturbance were felt. The wind shifted to southerly and the 

 barometer fell but as the disturbance began to recede to the eastward 

 it also began to occlude and the winds soon resumed their prevailing 

 northwesterly direction.
