up to the time of the closing up of the establishment, having been in con- 
finement over three years, and by which time they had become the 
blackest of black drum ; all the bands that were so conspicuous in their 
younger stage having disappeared entirely, although, for the last two 
years, the shark tank, (some seventy feet in length), in which they had 
been kept, was always flooded with strong sunlight in the morning and 
strong daylight during the afternoon, not to mention a flood of gaslight 
during the evening. The bottom of this tank consisted of clean and

drum at different points about my boat; they were evidently having a big 
oyster supper.”’

THE LAKE DRUM OR MALESHAGANAY. 
The fresh-water Drum, Haploidonotus grunniens, is always known in the 
Great Lakes by the name ‘‘Sheepshead.’’ In the Ohio River it is usually 
called ‘‘ White Perch’’ or ‘‘ Gray Perch,’’ often simply ‘‘ Perch.’’ In 
the lakes of Northern Indiana it is called ‘‘ Crocus,’’ evidently a corrup- 
tion of ‘‘ Croaker.’’ In the Southern States the name ‘‘ Drum’? pre- 
dominates ; that of ‘‘ Thunder-pumper,’’ also used for the bittern, Botau-
