ARRANGEMENT OF SCALES ON HEAD OF 
a, Pickerel; b, pike; 
DISTINGUISHING THE PIKES 
HE Aquarium is occasionally called upon to 
settle wagers of sport fishermen, as_ to 
whether their prize captures were pike or 
muskallunge. Quite as frequently the question 
is asked, What is the difference between a pick- 
erel and a pike? 
The most concise and lucid answer to these 
questions is an illustration appearing in a paper 
on the pikes, by William Converse Kendall of 
the U. S. Bureau of Fisheries, published in the 
Report of the Commissioner of Fisheries for 
1917. The illustration is here reproduced, for 
the benefit of our future disputants who may 
not be familiar with Mr. Kendall’s paper. 
First it will be noted that the pickerel, pike 
and muskallunge are all pikes—Duciidae. Sec- 
ondly, that the slight difference in the shape of 
the head would be of doubtful assistance to the 
angler in determining which species he had 
caught. Thirdly, that the only positive means 
of identification is by the squamation—the ar- 
rangement of scales—of the cheeks and _ ill 
covers. 
PIKES 
c, muskallunge. 
It will be observed that in the pickerel the 
cheek and gill cover are completely scaled; that 
in the muskallunge there are only a few scales 
behind the eye and on the upper half of the gill 
cover; while the pike is intermediate between the 
two, having the whole cheek and upper half of 
the gill cover sealed, the lower half of the gill 
cover being unscaled. 
The muskallunge is generally stated to be 
the largest of the pikes; but the common pike is 
known to have reached a greater weight, mus- 
kallunge not having been recorded as weighing 
over 100 pounds, while a 145-pound pike is on 
record. The muskallunge averages from twenty- 
five to eighty pounds, with a length of four 
feet, although it has been known to attain eight 
feet; the American pike runs from five to forty 
pounds and reaches a length of four feet; and 
the pickerel runs from about four to fourteen 
pounds, with a length of from one to two feet. 
Large specimens of the pike and pickerel may 
easily be mistaken for muskallunge, and the 
angler will find an identification key useful.

In commemoration of the one hundredth birth- 
day of Jenny Lind (October 6, 1820-November 
2, 1887) and of her first American concert, 
which was given in the Aquarium building 
(Castle Garden) in 1850, the Executive Com- 
mittee of the Jenny Lind Centennial Celebration 
opened an exhibition of her relics at the Aqua- 
rium on October 1, to continue for ten days. 
Owing to the great appreciation shown by the 
public, permission was asked and granted to 
extend the exhibition until October 28. During 
this time 163,151 persons visited the Aqua- 
_ rium and viewed this exhibit. 
Six museum cases of of the famous 
prima donna were shown, two handsome satin 
relics

flags loaned by the United Swedish Societies of 
New York were hung in appropriate places, one 
being the flag of Sweden, the other of America. 
Two pianos used by Jenny Lind at her concerts 
in America were exhibited—one a Chickering, 
belonging to Chickering & Sons, the other manu- 
factured by W. Geib (New York) and owned 
by Mrs. John W. Tobin of New York. A 
photograph was shown of a third piano which 
Jenny Lind took back to Sweden with her as a 
wedding gift to Mrs. Louise Munthe Broman, 
whose brother, Judge C. H. Munthe, now has 
it in his home near Stockholm. A dress of yel-
