were made and filed in the office, to be bound in books. 
These charts contain a rough sketch of the shape of the 
lake, give their name and location, dates of examination, 
kind of bottom and shores, temperature at top and bottom 
and surroundings, number and kinds of fish caught and 
how, their condition and what feeding upon, the kinds 
and condition of fish food inthe water, and recommend- 
ation as to kinds of fish to plant. This work has been 
continued each year until at present there are complete re- 
cords of upwards of four hundred lakes which have been 
examined, the reports of which are bound together in vol- 
umes indexed and easy of reference. These volumes are 
consulted in passing upon applications for fish plants in 
the waters. 
The capacity of the trout hatching house at Paris has 
already reached a million and a half, and a new house is 
recommended to increase the capacity to three and a half 
millions. 
The hatching and planting of whitefish, brook trout, 
lake trout, wall-eyed pike, carp, Loch Leven trout, land- 
locked salmon and California trout was continued through 
the years 1887 and 1888. In 1887 the first plant of German 
trout was made, and the rearing of this fish has been con- 
tinued ever since and much increased in later years. It 
seems to thrive in Michigan waters and has every appear- 
ance of being a hardy and a vigorous importation. 
In 1887 a new additional trout hatching house 40 by 824 
feet was built at Paris, at a cost of about $4,000 for the 
house and fittings. The old hatching house was disman- 
tled, but remains standing and is used for a store house 
and shop, It is capable of being restored and put in com- 
mission again on short notice and at small cost, if needed. 
The capacity of the Detroit whitefish house was increased 
by the addition of the jars removed from Petoskey, so that 
it now contains 525 jars, which would hatch eighty to 
ninety millions of whitefish a year.
