The ale is heated and the sugar and honey added. When cold the 

 rum and oil of almond, having been previously mixed are poured in

"Sugar" for moths. No. 2. 



A thick sugar made of brown sugar vrith a small quantity of rum. 



Dr. Leconte's poison for insects. 



Saturated alcoholic solution of arsenic 8 fl. oz. 

 Strychnine 1 2 grs. 



Crystallized carbolic acid I dr. 



Heavy benzine and alcohol enough to make one quart. 



Heavy benzine should be used (about 10-12 oz.), as lighter will not 

 mix with alcohol. The benzine should be tested for grease, by moistening 

 paper with it. If all greasy appearance does not disappear on drying 

 it shoiJd be rejected. This poison is to be applied to the insects in the 

 cabinet by an atomizer. 



A good mucilage. 



Take equal parts of gum arable and gum tragacanth, swell in water 

 and then dissolve by means of heat, then add a few drops of carbolic 

 acid and a few of glycerine. The carbolic acid prevents fermentation 

 or mould, the glycerine keeps it from cracking or scaling off when 

 dry. 



Thick flour paste added to common glue adheres well to glass as also 

 does the mucilage made of gum arable and gum tragacanth. 



"Electrical Cement." 



Melt together ten oz. of resin, two oz. of beeswax, two 02. of red 

 ochre, and add a teaspoonful of plaster of Paris. This is used hot for ce- 

 menting brass or wood to glass.
