Receipts from customs at New York.
--The receipts from customs at New York, for January, 1861, are less by just about one-half than for the same month last year.
The falling off of Southern trade at Northern ports may be said to have commenced substantially at the date of the Presidential election.
In November, 1859, the receipts from customs at New York were $2,184,000--in November, 1860, $1,806,000. In December, 1859, $2,854,000--in December, 1860, $1,192,000. In January, 1860, $3,914,000--in January, 1861, $2,068,000. The aggregate of difference in receipts of customs at New York for three months back, as compared with receipts for a corresponding period a year ago, is $3,686,000. Add to this the difference in such receipts in like periods at Boston
, (the former $265,000, the latter $231,000,) and we have an aggregate of $4,382,000, which would represent over twenty millions of dollars in value of foreign dutiable articles.
