direction. When the region had been injured either in capture or transport, the 

 nearest uninjured region to this was used. The scales were stored in envelopes on 

 which the length of the fish and other data were written. For microscopic study the 

 scales were cleaned and flattened between two slides. In calculating the proportional 

 lengths from the position of the winter rings^ the positions of the outer edges of the 

 winter rings were marked on strips of paper so placed that the edge of the paper 

 coincided with the camera lucida image of the antero-posterior diameter of the scale 

 in its anterior part. These strips were then placed on the apparatus devised by 

 Hjort and the proportional lengths read off. For each fish, at least two scales were 

 examined in this way. 



in. — THE FIRST year's GROWTH. 



A number of small Pollock, shown by their scales to be in their first year of growth 

 were obtained. The greater number of these were caught in a shore seine about two 

 fathoms in depth and twenty fathoms in length. The hauls were made in two 

 Localities and were as follows: 



A. — North of Wikon's beach, Campobello island. Wilsonfs beach is on the 

 western side of Campobello island and faces a stretch of tidal water lying between this 

 island and the islands to the west of it, often called by the fishermen "The Eiver". 

 Tiie Western shore of Campobello island descends somewhat abruptly, and, in conse- 

 quence, the tidal current comes close to the shore. The hauls were made at about 

 the time of low water on the morning of August 4, at which time many small pollock 

 ranging around 35 cm. in length were seen in schools inshore. The results of these 

 five hauls all made within a mile or two of each other, are grouped together and 

 labelled catch No. 19. The separate hauls are given below. 



Haul No. 1. — The seine was set a considerable distance from the shore so that the 

 corks went under. The catch consisted of four pollock under 11 cm. and 1 pollock 

 42 cm. total length, and one flounder. 



Haul No. 2. — The seine was set so that the cords just remained afloat. The catch 

 consisted of seventeen pollock between 28 and 47 cm. total length, and no other fish. 



Haul No. 3. — This was a short haul, the seine being set at about its own depth. 

 The catch consisted of a few flounders and skulpins. 



Haul No. Jf. — This was a deep haul, the seine being set at about twice its own 

 depth, the corks being completely under, on a beach covered with kelp. The catch 

 consisted of fifteen pollock under 11 cm. total length, four skulpins, four flounders, 

 and two sea ravens. 



Haul No. 5. — This haul was made in shallow water and went foul of rocks. The 

 catch consisted of a few flounders and a few skulpins. 



B. — Bliss island. These hauls were made on the shores of a small island in the 

 bay of Fundy, northeast of Campobello island and southwest of L'l!tang harbour, 

 where, as in the case af Wilson's beach, strong tides run. In all, six hauls were made 

 and the catches numbered 28 to 33. Three hauls were made at low water on the 

 evening of August 16, the seine being set in about its own depth. The hauls yielded 

 the following small gadoids: — 



Haul No. 1. — Two hake. 



Haul No. 2. — Two pollock, forty-four cod, numerous hake. 



Haul No. 3. — One pollock, two cod.
