of the loop, round it and up again on the inside, and then through 

 the smaller loop thus formed, thus making a thumb-knot. By 

 this means a simple noose is formed bj a thumb-knot at what 

 was the loose end, round the standing portion, the knot being on 

 the underneath side when the noose is made. The diameter of 

 the noose is about one-and-a-half inches. Treat the other end in 

 the same manner. 



When wetted and adjusted, these (viewed in plan) butterfly 

 nooses (Fig. V), should stand out at right angles to the stick, so 



Fig. V. 



that when the stick is planted upright in the water the nooses are 

 parallel to the surface of the water. Make two sets of these 

 nooses, thirty-six uprights with nooses in each set. 



Fasten all the sticks of each set together by twine, the length 

 ot t wme between two uprights being about eight inches ; the twine to 

 be fastened to the sticks at a distance of about four inches from the 

 pointed ends. 



To set the nooses.— The depth of the water must be twelve 

 to thirteen inches. In this depth of water drive in a willow stake, 

 iireak oft its top about one inch above the water and smear 

 the top with mud, so that it may not be conspicuous. With this 

 stake as a centre and radii of fourteen and twenty-four inches, de- 

 scribe two concentric circles. Then dig out the space between the 

 circumferences of the larger and smaller circles to a depth of nine 

 or ten inches, using a wooden spade of which the blade is the 

 exact depth. 



Erect one set of nooses along the inside of this trench, and the 

 other set along the outside. When in position, the nooses should 

 be parallel to the top of the water, but on a level with the natural 

 bottom, thar. is, on a level with the top of the trench (or not more 

 than half an inch above this level). The sticks should be about three 

 inches apart when set up. Keep the nooses at, what might vul- 

 garly be called, right angles to the circumference of the circles, 

 and place them chequerwise, the point of d noose being haK to 

 one inch distant from the outer circumference C, and the point of 

 e noose the same distance from the circumference B (Fig. VI).
