ing a residence of ten years in Sandwich, Cape Cod, where 
the facilities for that purpose are very abundant. 
It may be well to premise, that the distance, at this point 
of the cape, from one bay to the other, varies from five to ten 
miles, and the land is gradually elevated from each shore till 
it reaches the centre, and consequently the streams, for the 
most part arising from springs, are short, terminating in creeks 
upon the marshes. Many of these are of sufficient magnitude 
for mill sites, and are therefore crossed by permanent obstruc- 
tions; and hence it frequently happens, in the short space of 
a quarter of a mile, you find specimens of both, as they are 
familiarly called, the fresh and salt water trout. 
The following varieties in color and appearance have been 
observed. 1st. Those having the upper part and sides of a 
pale brown, gradually becoming less so, till it terminates in 
White on the under part, having a silvery appearance when first 
taken from the water, and covered with small, distinct scales ; 
the circular yellow and red spots very indistinct ; generally 
found in the marshy creeks, or in open streams, where the 
Sun has free access, They are well fed upon minnows and 
shrimps, have a plump appearance, and are the variety mostly 
Sought after by those who desire the trout, in its highest per- 
fection, for the table. They are taken, mostly, between the 
months of January and July. They vary in size from one 
fourth of a pound to four pounds ; but I have never seen one 
to exceed two and a half. 
2d. "Those having the upper part and sides of a dark 
brown, having a dark green appearance, terminating in white 
9r orange underneath, and covered more or less with round, 
Yellow spots, with a bright red centre, color varying according 
to the location ; and generally not so plump and well fed as 
those above mentioned. ^ 
3d. Those having the upper part and sides of either a light 
° dark brown, with spots more distinctly marked on the dark 
than the light ; underneath, the color uniformly ferruginous or 
orange,
