Winds. — Referring to the Eastern half of the January 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 equal that it will either be more Southerly 



or more Easterly or N. -Easterly.* 

 „ 2° & 4° S. „ M 2 to 1 that it will be more Southerly.

Current. — The January Chart for Square 303 shows a prevailing Westerly 

 Current of from 20 to 30 miles in 24 hours, and that it is stronger in the 

 Northern than in the Southern half of the square. Exceptional currents, 

 considerably stronger than the means shown on the chart, are sometimes 

 recorded. The chart shows a large per-centage of smooth sea in the 

 month of January. 



The above-named facts, taken together with the qualities of his ship 

 will enable the navigator to decide on his best route. 



Ships bound to the Northward should cross the Equator between 

 25° and 30° W., so as to avoid the light North-Easterly Winds which 

 sometimes blow near the South American coast in this month, and also to 

 pick up the fresh N.B. Trade, which prevails in that longitude between 

 4° and 6° N., but not farther to the Eastward. 



February. 



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

 Verd Islands, as the Western sides of Squares 39^ and 8 have stronger winds 

 than their Eastern sides. They should stand to the Southward in about 

 26° W., and when they meet the Southerly Wind, take the tack which 

 gives the most Southing, endeavouring not to cross the Equator to the 

 Westward of 28° W. 



Winds. — Eef erring to the Eastern half of the February 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° & 6° S. the probability is about equal that it will be more Southerly, 



Easterly, or North-Easteriy. 



„ 6° & 8° S. „ „ slightly in favour of its being more Easterly 



or North-Easterly. 



„ 8° & 10° 8. „ „ about 2 to 1 that it will be more Easterly 



or North-Easterly. 



Current. — The prevailing Current is still Westerly, averaging from 

 20 to 30 miles a day, and generally stronger in the Northern than in the 



• In working out these probabilities all obBervations of wind from North have been 

 considered as North-Easterly, and all from South have been oonsidered as Southerly. 

 The few observations from the Western half of the compass have not been included.
