THE GULF STREAM, 393 



30° to 35^ N., the Stream is reported to be unusually weak ia this month. 

 There is evidence of a Southerly set between 2V and 30' N., Eastward 

 of the Gulf Stream, as far as long. 70^ W. 



In April the Gulf Stream appears to commence at the mouth of the 

 Mississippi, flowing South-Eastwardly towards Cuba, where it is turned 

 Eastward, and then to the N.E. and North round Florida. Commencing 

 with a rate of 22 miles, it becomes 36 miles off Cuba, and 48 miles off 

 Florida, maintaining this rate to lat. 32'^ N. Its direction is now to the 

 N.E., but its rate is undiminished to lat. 35'^ N. Beyond this, observa- 

 tions indicate the current to long. 58^ W. in 38' N. It appears to extend 

 from the coast to 65^ W. on the parallel of 36^ N. The counter-current 

 to the S.W. is shown considerably farther Eastward than in the previous 

 months, being to the East of the 70th meridian in lat. 31' N. Its rate is 

 from 11 to 22 miles. 



In Mmj it may be considered to commence from the Delta of the Missis- 

 sippi, with a rate of only 16 miles, but flowing S.S.E. it becomes 27 miles; 

 then E.S.E. 35 miles ; and passes between Florida Reefs and Cuba at the 

 rate of 44 miles. Between Florida and the Bahamas it has the greatest 

 mean strength yet noticed, 64 miles. Thence it continues North, N.N.E., 

 N.E., and E.N.E., at a mean rate of 40 miles, until it reaches lat. 37' N., 

 long. 70° W. Eastward there are indications of this current across the 

 Atlantic, as far as the Azores, the rates given varying from 6 to 29 miles. 

 On the whole, the Stream appears to be stronger, and to extend farther 

 into the open ocean, than in April. There is evidence of a remarkable 

 overflow from the Gulf Stream, setting E.S.E., at from 14 to 22 miles per 

 day, between lat. 28' and 33' N., shown as far as 70' W. ; also into the 

 Santaren Channel, as if all the water could not pass with the main 

 Btr>-:a:n. 



In June it may be considered to commence off the Mississippi at 12 miles 

 per day. Thence it flows S.E. towards Cuba, at from 17 to 38 miles, then 

 East between Florida Reefs and Cuba, at 50 miles. From lat. 25" to 30° N. 

 there are no observations of it. From lat. 30^ N. it flows North-Easterly 

 to lat. 35° N., at from 46 to 63 miles. Between 35' and 40° N. it becomes 

 more Easterly, and its rate is variously given from 14 to 48 miles. It can 

 be traced to long. 45' W. in lat. 37' N. There is no evidence that it 

 reaches the Azores. It has greater extension Southward between long, 

 55° and 70° W. than has been noted hitherto. There is no evidence of au 

 overflow North of the Bahamas, although the Stream appears to be quite 

 as strong as in May. 



In Jiili/ the Gulf Stream may still be traced from the Mississippi, flowing 

 South-Easterly towards Cuba, at a rate of about 24 miles. Between 

 Florida Reefs and Cuba it attains 51 miles, and from 25' to 30° N. it has 

 been found to average 72 miles nearly due North. Thence it flows East- 

 ward of North to lat. 36° N. in long. 70° W., at a rate of 30 to 43 miles. 

 Its set is now Eastward, and can be traced to long. 35' W., but the obser- 

 vations are neither numerous nor consistent. On the whole it appears 

 that the Gulf Stream is very strong this month, and that its Southern 

 limit is in lat. 36" N., between long. 40° and 72° W.
