Lake county, last fall, and which at that time measured from one 
to three inches in length, are found to have grown rapidly; some 
have been caught within a few weeks that measured ten inches. 
frequent occurrence to capture specimens weighing from fifty to 
one hundred pounds. 
The young trout with which the streams of Santa Cruz county 
have been stocked are natives, coming from the McCloud river. 
This species is regarded as the most vigorous, and frequently 
attains the weight of five pounds. It is said to have a growth o 
ten inches in one year. It is reported that the osiris miersi in 
charge of the Yo Semite valley have decided to plant the McCloud 
river trout in the streams of the Yo Semite reservation. e 
experiments with the brook trout of the Atlantic States in the 
streams of the coast range, have not been satisfactory; this is 
owing, quitely likely, to two causes: first, too high a mean tem- 
perature in the waters of said streams; and second, through the 
impurities they contain, which must be especially obnoxious to 
so dainty a fish during the fall months when the streams are low, 
muddy and warm, and the water flavored more or less. by thè 
bituminous shales through or over which they frequently flow, 
and out of which ooze numerous small springs, often covered with 
an oily slime or scum. Experiments with eastern trout are much 
more likely to meet with success in the loftier regions of the 
Sierra Nevada, in the clear cold waters of a granitic formation, 
nearer the line of almost perpetual snow. 
Santa Cruz fishermen sometimes ee a few mackerel and 
shad in the neighboring waters of the . The former are a 
native, the latter an introduced fish, but Ge scarce. For some 
reason the mackerel do not strike in toward the shore to any 
considerable extent. In consequence of this, the few that are 
sent to the San Francisco market are sold at fancy prices

` York, and it doubtless obtained elsewhere. It will be well for us 
to endeavor to arrive at the reasons. To my mind the following, 
first stated by me in the New York Tribune, may very pro roperly 
be urged: rst. The very general failure of the a pple crop in 
1877, as exemplified in the reports for that year, wii we find 
both in the Proceedings of the Michigan Pomological Society 
and in those of the American Pomological Society. This failure
