 Pennsylvania had done conditionally. 



Besides their work in shad hatching the commissioners continued to 

 struggle with the problem of perfect fishways and in the fall of 1873, 

 completed one in the Columbia dam, which they believed would ulti- 

 mately prove successful, and indeed for a time, while the water was high, 

 it looked as though it would be, and it was in fact a great advance over 

 anything that had preceded it. Its imperfections, however, are but put 

 in the commissioners' own words: "We are firmly convinced," they said 

 in their report for 1874, "that our fishway, as it stood in 1874, was opera- 

 tive in a high stage of water; we are just as firmly convinced that during 

 a low stage our fishway was inoperative and inefficient." 



To better this weakness alterations were made at an expense of some 

 $4,000. But even these failed to give satisfactory results.
