46 FISH-CULTURAL ASSOCIATION. 
one day a young fellow crossing the dam with a long string of 
these little fish that would more than fill a peck measure, Mun- 
son took out his rule and measured about half a dozen of them, 
and found them to vary little from three inches in length. These 
young fish were taken that season in numbers that threatened to 
seriously affect the abundance of the adults, and upon petition, 
the legislature at its next session forbade their capture. The 
occurrence of parr of the same or nearly the same size in the 
fall as in the spring, is a noteworthy and at first a puzzling cir- 
cumstance. Spawning takes place but once year, that is beyond 
question. Do the young fry grow unequally, part of them 
attaining in six months the same size that others do in a year, 
or is there a lapse of six months in their lives without any con- 
siderable growth? I think the first supposition is not admissible, 
because we have never met with the intermediate sizes that must 
have been present. It seems possible, therefore, that their 
growth is almost wholly accomplished in the warm season and 
is nearly suspended in the winter. 
Second class. Seven to eight inches in length and weighing 
three to four ounces; bars and red spots still plainly visible, and 
nearly as distinct as inthe first class. They yield a copious supply 
of milt, and a few of them are found commonly ‘on the spawn- 
ing beds, attending or seeking to attend the female salmon in 
the act of spawning. They occur at the same time, though not 
commonly in company with the smaller fish of class one, both 
in fall and spring. 
Third class. A little larger than class two, measuring about 
ten inches, and weighing seven or eight ounces. Barsand spots 
still visible but very faint. All males, and yielding milt cop- 
iously. Observed occasionally in October and November. 
This form approaches closely the “smolt” of the river salmon. 
Fourth class. About thirteen inches in lengthand one pound in 
weight. Reproductive functions dormant, organs little devel- 
oped and sex unknown. They are uniform in appearance as 
well as size, but are not numerous and appear irregularly, rarely 
more than half a dozen of them ina single season. Barren in- 
dividuals of larger size, sometimes as large as seventeen inches 
in length, and thirty ounces in weight, met with rarely, and only
