Description
English: Equipment of McDonald automatic tidal boxes, for hatching cod, Boothbay Harbor, Me. Shows boxes lifted out of troughs and bottom upward on farther tables. The bottom is of scrim, and by means of cleats is held 1 1/2 inches above the bottom of the trough at the center. By an arrangement of partitions at the head of the trough the eggs receive the supply of water through the scrim bottoms of the boxes, also through a small hole in one end of the box. The distinctive feature of the apparatus, whence it is called 'tidal,' is the automatic siphon outflow, by menas of which the water is alternately drawn down and replenished. Standpipe with siphon cap is shown near troughs; waste trough below
