extent that he could not believe that it was a fair repre- 
sentation of the fauna of the creek, and wrote to know if 
other animal life than that which naturally accompanied 
the plants had not been placed in the can, but none had 
been introduced except those contained in the plant when 
gathered. Shrimp were so numerous in the moss that 
one could not raise a handful of it without noticing the 
very large number of these creatures present. The water 
from the can was poured into an aquarium and at once 
‘‘numerous examples of the minute crustacean cyclops 
were observed, resting against its glass sides or darting 
swiftly through the water, the females bearing on each 
side of them the ovoid sac of eggs which forms so con- 
spicuous a feature of their appearance.” 
Prof. Peck, the State Botanist, who examined the 
aquatic plants from Caledonia, said: “There is among 
the mosses one of special interest, both because of its 
rare occurrence and because of the noticeable coincidence 
between its abundant growth there and the abundance 
of animal life that accompaniesit. * * It isknown 
to botanists by the name Aypuum noteraphilum, or 
moisture-loving moss. Franklin and Lancaster counties, 
Pennsylvania, are its previously reported localities, 
where it is said to grow in limestone springs. It was dis- 
covered in the Caledonia Creek several yearsago * * * 
but up to the present time this remains its only known 
locality in our State.” Prof. Peck advises that in trans- 
planting this moss, limestone waters should be selected, 
although one of the mosses associated with it at Caledo- 
nia occurs in waters free from lime. Prof. Lintner says 
that the small crustacez of the family Gammarizde un- 
dergo no metamorphoses after their escape from the egg, 
and therefore give promise of no difficulty in their pro- 
pagation, and he thinks that in time every order for 
5,000 brook trout will be accompanied with an order for 
100,000 shrimps. The food of the shrimps is in doubt, 
“but they are believed to be principally vegetable feed-
