1921] SHROSBREE, NEW SERIES OF BIRD GROUPS. 33 



We were up early next morning. Mr. Ochsner and myself went to 

 Darlington to get packing boxes and some rough lumber for crating the 

 nests and limbs, while Mr. Stoddard went to the woods to secure one 

 more nest with some young birds. We were having a rather strenuous 

 time, and did not wish to stay to prepare our birds. We soon had the 

 nests and trees packed and at the express office. We had placed the 

 young birds in alcohol and packed the adult birds and eggs in the Ford 

 along with our collecting outfit, and l)y 2 :00 P. M. we had started on our 

 way back to Prairie du Sac, arriving there at 7 :00 P. M.

We had travelled in all 1 54 miles and had secured the specimens and 

 all necessary accessories for a large bird group, in thirty-seven hours. 

 This trip serves to emphasize the value of a light truck in field work. 



Having skinned the Night Herons, we prepared to make our final 

 "raid" on the Cormorants. I first secured the services of Mr. Lawrence 

 Keller, a farmer near Prairie du Sac, who owned a large flat-bottomed 

 power boat, just the thing we needed for the work in hand. Fortunately 

 for us, Mr. Keller was as much interested in the work as anv of us.
