Mr. Albert Gastrow met us at the place of embarkation. He had al- 

 ready secured a good mess of fish for lunch. Mr. Ochsner turned out 

 with his indispensable "Lizzie" into which he loaded all our equipment 

 which we transferred to the boat moored two miles up the river. 



Our collecting party consisted of Lawrence Keller, Captain of the
