2. All the motion of the sea on that shore depends upon the 
wind. Its agencies are twofold; first, the daily change of sea and 
land wind, the former beginning to blow in the morning about 
eight o’clock, the latter in the evening between six and nine. 
The latter is much more constant, and being also more powerful, 
it depresses, every evening, the level of the sea all along the coast 
m one to two feet. But there is, secondly, another, a yearly 
change of the winds, viz.: a prevailing northerly wind in winter, i 
particularly in December, January, and February, and a preval- 
ing southerly wind in summer. This great change produces 
this effect, that in the season of the North, as they call it there, 
the level of the sea is constantly, on the average, eight feet 
higher than in summer. 
How much this change bears also upon the organic life of the 
sea coast, is evident. I will only state that during the last week 
of May and the first of June, in one place not larger than an acre, 
- more than a hundred Actiniz and Holothurie died, because left 
upon dry land; not-to speak of the thousands of other animals, 
fishes, echini, etc., and of sea-plants which died in those natural 
asins near the sea, where the water, cut off from the refreshing 
_ O¢ean, was overheated by the nearly perpendicular rays of the 
tropical sun. The rising of the land from the waves, the same

Swept, and not only all the dead remains but many living shell- 
and large blocks of corals, are dashed against the iron- 
coast and thrown up on dry land. This is the season 
dreaded equally by the Haytian coasters and the merchant vessel.
