ceive the least motes in it; then put it into an 

 earthern pot to ferment, scum it fourorfive days, 

 as often as any thing rises, and when no more 

 comes, change it into a fresh earthen vessel, and 

 preserve it for use in this manner. Take what 

 quantity you think fit, put it in an earthen pipkin, 

 add a third part of capons or goose grease to it, 

 well clarified, or oil of walnuts, which is better, 

 incorporate them on a gentle fire, and stir it con- 

 tinually till it is cold, and thus it is finished. 



To prevent frost: take a quarter of as much 

 oil of Pretoleum as you do goose grease, and no 

 cold will congeal it. 



How to use Bird-Lime. 



When your lime is cold, take your rods and 

 warm them a little over the fire; then take your 

 lime and wind about the top of your rods, then 

 draw your rods asunder one from another, and 

 close them again, continually plying and work- 

 ing them together, till by smearing one upon ano- 

 ther, you have equally bestowed on each rod a 

 sufficient proportion of lime. 



If you lime any strings, do it when the lime is 

 hot and at the thinnest, besmearing the strings 

 on all sides by folding them together, and unfold- 

 ing them again. 



If you lime straws, it must be done likewise 

 when the lime is very hot, doing a great quantity 

 together, as many as you can well grasp in your 

 hand, tossing and working them before the fire 

 till they are all besmeared, every straw having its 

 due proportion of lime; having so done, put them 

 up in cases of leather till you have occasion to use 

 them.
