MACKEREL.
When red mullet are abundant in fishmongers' shops, a fine mackerel season may be expected. The early mackerel are frequently attended by a few mullet; and whenever they nearly, if not altogether, equal the mackerel in number, the circumstance is generally the presage of the approach of great shoals of mackerel.
The course of herrings and mackerel is traced by their eggs, which, during a calm, may be seen floating on the surface of the water, like saw-dust, amidst an appearance like the wake or track of a vessel.
