Notes of Salmon Hatching. By G. Henry Kinahan, F. R. G. S. I. 



During the last two seasons I have been able to watch the artificial 

 propagation of Salmon, and perhaps Notes that were made from time to 

 time may interest some of the Members of the Society. 



The artificial breeding I have seen is that carried on by Mr. Miller, 

 at Galway; Captain O'Hara, at Inver; and Major Horsefall, at Screeb. 

 The boxes, &c, of Mr. Miller have been ably described by Dr. Buck- 

 land (see "Land and Water"), therefore at the present I shall pass them 

 by. Captain O'Hara' s 

 boxes were in the open g * 



tain stream that flows 

 into the south-east 

 corner of Lough In- 

 vernagleragh. Across 

 this stream an em- 

 bankment was formed 

 to construct a reser- 

 voir, out of which the 

 boxes were supplied. 

 For the arrange- 

 ment of the boxes, &c, 

 I shall refer to the ac- 

 companying figures, 1 

 and 2 (exhibited to 

 the meeting). There 

 are twenty-four boxes, 

 placed in tiers of six 

 two tiers being coupled 



by a filter box. Each box is four feet long, by one foot wide, and four 

 inches deep ; and in the bottom of each box two inches of well-boiled 

 and washed gravel is laid, on which 

 the eggs are placed. Fig. No. 2 is 

 an isometrical view of two of these 

 tiers of boxes with their coupling 

 filter. The filter boxes (A and A, 

 Fig. No. 1) are fed by a two-inch 

 gutta percha pipe (B B) that leads 

 from the reservoir. This pipe is 

 furnished with two wooden cocks 

 (a and a) to regulate the flow of 

 water. From each filter there are 

 four cocks (b b b b) to supply the 



hatching boxes, every three boxes having a special stream. On referring to 

 the drawings (figs. 1 and 2), it will be seen that the boxes are arranged
