26 DAVENPORT ACADEMY OF NATURAL SCIENCES. 



The party assembled at the foot of Brady Street, and about 

 nine o'clock a. m. started down the river on board of Mr. Oifer- 

 mann's horse power boat, "River Horse." After a pleasant trip 

 of an hour, the party was landed near the head of Credit Isl- 

 and, about three miles below town. The weather was delight- 

 ful, and the place beautifully adapted for a picnic. Everyone 

 seemed to thoroughly enjoy the day, and it was seven o'clock p. 

 M. when the boat started on the return trip. 



A large number of cattle are now pastured on the Island, so 

 that the collecting is not as good as formerly. A conside- 

 rable number of interesting insects were picked up, embracing 

 about a dozen species of beetles not before known from this 

 locahty. A single immature mole cricket ( Gryllotalpa horealis) 

 was found under a stick of wood in a moist place. We know of 

 but one other specimen, which Prof. Sheldon found near French 

 tfe Davies' saw mill several years ago. The only shells collected 

 were some immature specimens of Physa heterostropha and a 

 few young Helices. A few years ago there was an abundance of 

 Helix multilineata on this Island, but the presence of cattle 

 has rendered them scarce. A large number of frogs {Rana 

 halecina Kalm.) were noticed high up on dry land. Ko plants 

 of any special interest were noted.
