 rodman. The Assistant Curatcir also spent two days in the northern 

 lUiiiuis lake reynon nmkii)^' detailed studies of the floating bof^ of these 

 lakes and their peat and marl deposits, in order to obtain data for 

 making a model of a glacial lake. Besides the study material brought in, 

 some additions to the permanent collections were thus procxired. 



In October the Assistant Curator of Ichthyolojry and Herpctolojjy, 

 accooTAnii li hy Toxidermjst Pray, spent nearly two weeks in Wis- 

 oonstii : material for exhibition purposes, the work being carried 



on alon^ the Mississippi River, chiefly on I-Ake Pej)in. 60 specimens for 

 mounting were obtained, reprcsentinR Iwcnty-scvcn of the important 

 food fishes of the Mississippi Valley. This n^terial will cover the 

 larger part of at least one side of a panel case, and will serve as the 

 basis of three or four groups, for which the accessory material was also 

 gmthered. The .success of this cxi>edilion depended to a considerable 

 degree upon the cooperation of certain memlxrrs of the Association of 

 Commercial Fishermen and Clammcrs. Upon the request of the 

 Association, the Museum sent as a loan a collection of twenty-two 

 mounted food fishes, with labels, to the annual meeting of this organiza- 

 tion held in La Crosse on November 30th. The fishes were also exhibited 

 in the High School of that city. On three different occasions the lagoon 

 in Jackson Park, adjacent to the Museum, was seined and nimierous 

 specimens were obtained, some of which have been i- d for exhibi- 



tion. The A.ssistant Curator has collected a consjutiauic number of 

 local &shcs, amphibians, and reptiles in the vicinity of Chicago while 

 engaged in his work for the exhibition scries. Frequent one-day trips 

 w er e made and one week in August was spent in the sand dunes of 

 Indiana collecting material for this DiNnsion. As soon as the summer 

 had advanced sufTiciently to make collecting profitable, a number of 

 field trips were made for insect group material by the Assistant Curator 

 of Entomeology and his assistant. For this purpose Palos Park, Illinois, 

 was visited at inter\'als in order to obtain s- ns, particularly 



dragonflies, and accessories for a group illusiias...;;; the insect life 

 of ponds. To r e pr e sent the most conspicuous insects found in the 

 \'icinity of stta!! nmning streams, the region between New Lenox and 

 Joliet was 1; visited at inter\'als. Toward the end of summer 



8eN*eral trips were made to Edgebrook and other nearby places for 

 material suitable for a group of tomato worm moths. Several dajrs 

 were also spent at Miller, Indiana, in order to secure the insects and 

 accM Sori es t>*pical of sand areas, but, as the collecting season had already 

 wdl advanced, it was not possible to secure a scries of some of the early 

 stages of tbe most characteristic forms. As a result of these trips eooogh
