VERMONT AGRICULTURAL REPORT. 103 



Perforated zinc costs about 40c. per square foot. Double 

 warp cloth, galvanized, costs about 8c. per square foot. 24 mesh 

 galvanized wire cloth costs about 10c. per square foot. Prices on 

 all dependent upon the quantity purchased. In ordering perfo- 

 rated metal, give the size of pieces required, in order that the 

 stock sent you can be cut economically. 



Use 3 oz. copper tacks to fasten perforated metal or wire 

 cloth on to frames. If not easily obtainable, use 3 oz. tinned 

 carpet tacks. Most all of the stock required in making trays and 

 other equipment can be gotten out of the waste lumber from the 

 troughs. 



PAINTING. 



Paint troughs inside and out, and all trays and other equip- 

 ment which comes in contact with water, with two coats of tur- 

 pentine asphaltum paint. A suitable quality of paint costs from 

 50 cents to 60 cents per gallon. 



TOOLS. 



Having equipped a hatchery connected with a constant and 

 suitable water supply, you are ready for the eggs, but there are 

 some hatcher)' tools which will be convenient, most of which you 

 can make yourself. Figures 9 and 10 show two forms of egg 

 pickers with which to pick out dead eggs. Figure 9 is made by 

 taking a piece of galvanized sheet iron about 22 guage and cutting 

 it into a strip about 12 inches long, 1 to \]/ z inches wide at the 

 centre and tapering to about yi in. wide at each end. Bring the 

 two ends together, as shown in the figure. Figure 10 is a more 

 elaborate form of picker made by cutting the tweezers out of a 

 solid piece of clear pine about 6 or 7 inches long and attaching to 

 them some fine wires with rings at the ends about }i inch in 

 diameter. A more simple picker can be cut out by trimming 

 down a clothes pin or cutting plain wooden tweezers out of a piece 

 of pine. Nearly every fish culturist makes a picker to suit him- 

 self. 



Figures 11 and 12 are scarf nets used for picking up eggs 

 or fry and for cleaning troughs, etc. The rectangular net should 

 be about 10 inches wide by 9 or 10 inches deep. It is made by 

 bending a wire into the form shown, fastening the wire to a 

 light handle and covering with mosquito netting or bobinet. 

 The bobinet is preferable and costs from 45 to 75c. per 

 yard, 54 inches wide. The side of the wire frame opposite 

 the handle should first be covered with some coarse material to 

 which the bobinet can be fastened. This is because the bobi- 

 net would wear out too quickly if sewed directly to the bottom 

 of the frame. The triangular net, figure 12, is much smaller 

 than the other and does not require so heavy a wire frame ; 

 either 4 or 5 inches to a side is a good dimension to follow.
