486 PASSAGES OVER THE ATLANTIC. 



on the Eastern Bvde of Square 3; they should then stand to the Southward 

 in about 26° W., taking the tack which gives the most Southing when the 

 wind draws Southerly, 



Winds. — Referring to the Eastern half of the April Wind Chart for 

 Square 303, and taking S.E. by E. as a central point, then, whem the 

 Wind is not from that point : — 



Between 0^ A 4° S. the prob. is about 3 to 1 that it will be more E.-ly or N.E.-ly.

„ 6° & 8° S. „ „ 4 to 3 „ „ Southerly. 



8° & 10^ S. „ „ 3 to 2 „ „ E.-ly. or N.E.-ly. 



Current. — The prevailing Current is still Westerly, at a rate of from 20 

 to 30 miles in 24 hours, exceptional currents being stronger ; it is strongest 

 between 2° and 8° S. There is a good deal of North-Easterly swell in the 

 N.E. part of Square 303, and of smooth sea in its S.E. part. 



Near the South American coast there is much light North-Easterly 

 Wind, and it does not seem likely that a ship would have great difficulty 

 in getting to the Southward there ; still the wind is lighter in Square 303 

 than in Square 302, and the Remarks on Square 303 show that ships 

 which cross to the Westward of 30° W. are sometimes hampered ; it 

 would therefore be well not to cross the Equator to the Westward of 27° 

 or 28° W. 



Ships bound to the Northward should cross the Equator between 25° and 

 30° W., so as to avoid the large amount of light North-Easterly Wind 

 which is recorded in Square 303, and the light North- Westerly Winds ard 

 Calms which are common on the Eastern side of Square 3. 



May. 



Ships bound to the Southward should pass to the Westward of the Cape 

 Verd Islands, where the May diagram and chart show the Wind to be 

 stronger than to the Eastward. In Square 3 the North-Easterly Wind 

 prevails to 4° N., and is stronger between 25° and 30° W. than between 

 20° and 25° W. 



Winds. — Referring to the Eastern half of the May Wind Chart for 

 Square 303, and taking S.E. by E. as a central point, then, when the 

 Wind is not from that point : — 



Between 0'' & 2° S. the prob. is about 2 to 1 that it will be more E.-ly or N.E.-ly.

From October to April the wind draws more Easterly in the Southern 

 part of the square, but from May to November it draws more Southerly. 



Current. — The Westerly Current is stronger than in previous months, 

 and frequently exceeds 30 miles in 24 hours ; it is strongest between 2" 

 and 6° S. The sea is also higher than in previous mouths.
