REPORT OF COMMISSIONERS OF INLAND FISHERIES. 41 
latter being the width of the goods as it comes from the factory. By 
making the sack of this size, it was necessary to have only two seams— 
one up the side, the other around the bottom of the bag. This did away 
with the pockets and corners which were so troublesome in the square 
bags last year. Along the bottom seam, on the outside of the bag, was 
sewed a piece of drilling four inches wide. This drilling was turned over 
a wooden hoop (child’s rolling hoop), which was a little larger in diameter 
than the bag. The hoop kept the bottom taut, while it also furnished a 
strong attachment for the ropes necessary to hold the bag in place. Ina 
like manner another hoop kept the mouth of the bag open. 
“The Support of the Bag.—On the inside wall of each pontoon, and six 
inches above the water, there is a cleat which runs lengthwise. Every 
four feet of these cleats a 2x6 plank was laid across the well and fastened 
securely. To the under side of each plank were nailed three posts four 
feet long—one at each end and one in the middle (see diagram). To make 
the frame still stronger, the submerged free ends of the posts hanging 
from consecutive planks were joined together by scantling pieces, Brass 
screw-eyes were screwed into the bottom of each post. 
“The bag was held in the frame just as the bowl or pocket of a fish- 
pound is secured. The top hoop of the bag was fastened with strings to 
the planks above (see diagram). The bottom was drawn down and the 
side of the bag stretched by means of ‘down hauls’ or ropes which rove 
through the screw-eyes in the posts. In this manner the bag was held 
so securely that there was little danger of the wind or tide carrying the 
cloth into the fan which was suspended in it. At the same time, it was 
a very simple matter to remove it whenever desired. 
“ B. The Mechanism (fan, belts, shaft, etc.) for Stirring the Water. 
“To keep the fry from settling to the bottom of the bag, a simple two- 
bladed fan, similar to those so often seen in restaurants for circulating air, 
was suspended in the bag and revolved slowly. The blades (F’) of the fan 
(see diagram) were 14m. x5m., made of cypress, and screwed firmly to a 
piece of maple (G), one end of which fitted snugly into the %-inch Tee 
(77). The blades were then set on angles and opposite to each other. The 
shaft of the fan was made of two pieces of galvanized gas-pipe, each three 
feet long, and of different sizes. One end of the lower half (%%-inch pipe) 
was screwed into the Tee, and the other was joined to the upper pipe (%4- 
inch pipe) by a reducing coupling. The whole was then suspended in the 
bag by means of some 2x3 pieces, as shown in the diagram—the reducing
