To quickly assess the difficulty of the text, read a short excerpt:
After several ripe females and some ripe males are collected, a female is taken, and the body slime, which will interfere with inipreguation if it falls into the pan, is carefully removed. The spawn-taker then grasps the fish firmly in his left hand, just forward of the tail, with the back of the hand downward, the fingers outward, the thumb above and pointing outward, the head of the fish being toward the spawn-taker's body. The right hand is placed under the fish just back of the pectoral fin...s, with the wrist pressing the head of the fish firmly against the body, the thumb outward, fingers inward, thus grasping the upper abdomen firmly. The fish is now at an angle of nearly 45^, the body forming a modified crescent, with the vent within 4 or 5 inches of the bottom of the pan. This position of the fish's body brings pressure on the abdomen^ facilitates the flow of the eggs through gravity and the opening of the vent, and prevents injury to them from falling too far. (See plate 34. ) Gentle pressure being now applied, the eggs flow in a steady, liquid stream about a quarter of an inch in diameter, and a considerable portion of them will be procured before the hand need be moved.
