The following cut and table show the situation of the concentrated counter-trade in March.

We see from this table that its focus had extended west in Florida over Fort Barrancas, and over Baton Rouge in Louisiana; N. W. to Forts Towson and Gibson in the Indian Territory, and Smith in Arkansas; north to St. Louis Arsenal at St. Louis, and to Newport barracks in Kentucky; but it was spread over a larger surface east of the mountains. Its greatest progress for the month, was a west and north-west progress.
In April, we find it had progressed rapidly west and north-west, and its position is shown by the following cut and table.
TABLE V.
| JAN. | FEBR. | MAR. | APRIL. | MAY. | JUNE. | JULY. | |
| Fort Riley, Kansas | 0.00 | 0.94 | 1.86 | 4.55 | 4.35 | 1.10 | 0.00 |
| Fort Leavenworth, Kansas | 0.04 | 1.78 | 1.33 | 3.35 | 5.55 | 4.50 | 0.18 |
| Mean | 0.72 | 1.01 | 1.61 | 2.74 | 3.62 | 5.80 | 3.15 |
| Alleghany Arsenal, Pittsburgh | 2.23 | 2.33 | 2.82 | 4.21 | 2.24 | 2.06 | 1.45 |
| Mean | 2.18 | 2.17 | 2.70 | 3.10 | 3.58 | 3.56 | 2.97 |
| Fort Columbus, New York Harbor | 2.60 | 4.00 | 0.70 | 8.80 | 7.70 | 2.20 | 1.90 |

| Fort Independence, Boston | 2.50 | 3.36 | 2.55 | 5.40 | 4.28 | 2.00 | |
| West Point. | 3.52 | 5.04 | 2.81 | 10.53 | 2.00 | 1.62 | |
| Mean | 3.50 | 3.44 | 3.71 | 4.55 | 6.18 | 4.79 |
We see, too, that both east and west of the mountains, its focus of precipitation was one month in advance of the mean. At all the stations where the greatest fall was in March, it should have been in April, and the fall at those points was greatly in excess of the usual quantity. And the same was true of stations reached in April. The concentrated trade, instead of spreading out, and precipitating over the whole south-eastern portion of the continent (its normal condition), was gathered into a wave of greater volume, resulting in greater precipitation, and was rapidly hastening its curve to the west over Texas, and to the north-west over the Indian Territory, and northward on its usual curve to the north and east of them.
