Under this trade during this month, and at the same posts, the fall of rain was as follows, compared with the mean:-- TABLE II. -------------------------------------------------------------- | JANUARY. | FEBR'Y. | MARCH. | -------------------------------------------------------------- | 1854. | Mean.| 1854. | Mean.| 1854.| Mean.| -------------------------------------------------------------- Key West. | 1.77 | 2.86 | 2.55 | 1.38 | 0.51 | 4.21 | Fort Myers. | 1.15 | 3.90 | 4.70 | 2.16 | 0.20 | 4.60 | " Brooke. | 3.88 | 2.20 | 6.89 | 3.01 | 2.44 | 3.37 | " Mead. | 1.30 | 1.07 | 2.21 | 1.01 | 1.85 | 1.64 | " Pierce. | 3.55 | 4.45 | 3.40 | 2.72 | 1.05 | 3.01 | " Barrancas. | 3.45 | 3.87 | 5.55 | 4.95 | 7.21 | 5.87 | Mt.

In April, the inter-tropical belt appeared at that point, and went on increasing till September. As the counter-trade commenced moving north in February, an increased precipitation above the mean commenced at all the more southern stations under the concentrated-trade--an earnest of that irregularity which followed, and marked the season as the most excessive of the century. In March, the intervening drought appeared at the other posts on the peninsula, and also at Fort Moultrie, followed _much more closely than usual_, by the inter-tropical belt of rains. In April, the drought appeared at Fort Barrancas and Mount Vernon Arsenal (the wave of precipitation having moved to the west), and slightly in comparison at Baton Rouge.
