FOR PLEASURE AND PROFIT. 101 



same fall presents very little, if any, difficulty to the pisci- 

 cultural engineer; in other words, the erection of a fish-pass 

 which would transform this: beautiful sheet of water, four 

 miles long by one mile wide, into a salmon loch would be 

 quite a simple matter, and not an expensive one either. 

 Astoimding as these two cases are, they only go to form ex- 

 amples of many others distributed over the whole of the 

 British Isles, and when we consider, in addition, the miles and 

 miles of river and stream that await treatment at the hands 

 of modern practical piscicultural engineers, we better realise 

 the immense possibilities associated with the encouragement 

 of salmon and sear-trout into inland waters at present inacces- 

 sible to them. 



I am not forgetting that difficulties other than those of an 

 engineering character occur ; but they are surmountable also, 

 even though they be of ai legal nature. And, the difficulties 

 being surmountable, it is> more 1 than strange to me that the 

 possibilities are not turned to more practical account. Let 

 us look at the matter in another light and let me suppose, 

 for the purpose of illustration, that ai certain sheep farmer has 

 many thousand acres 1 of admirable pasture land, and that it 

 only requires! to form a roadway to such pasture land in order 

 to ensure the coming of a magnificent flock of sheep each year, 

 and, comparatively speaking, free of expense. Need I ask 

 whether or not the farmer would form the roadway, if at all 

 possible? Yet, substitute salmon and trout for sheep, and, 

 although the possibilities in this latter casie are actually wuhin 

 reach, they are again and again, time out of number, absolutely 

 neglected. 



But such neglect does not always occur ; and, in referring to 

 what has been done and what is being done in connection with 

 the opening out of water to migratory Salmonidse, I shall en- 

 deavc<ur to show you how similar improvements could be 

 made elsewhere. And let me alsoi say at once that the Work 

 of planning and making a fishrpass or big dam. is best carried 

 out under the personal superintendence of an expert, and I 

 know of nr>' better man in this connection tham Mr. P. D.
