6. Dissolve i ounce common salt in i 

 quart of water; bring to a boil, and put 

 in i}( pounds gum shellac. When it 

 shall be dissolved, pour into cold water 

 and work like wax. Make into small 

 sticks. This will make crockery as good 

 as new. 7. Steep Russian isinglass 24 

 hours in white brandy ; gently boil and 

 stir the mixture until it is well compound- 

 ed, and a drop of it, cooled, will become 

 a very thick jelly; then strain it through 

 a linen cloth, and cork it up closely. A 

 gentle heat will dissolve it into a colorless 

 fluid. Broken dishes, united with it, will 

 break elsewhere, rather than separate in 

 the old fracture. To apply it, rub the 

 edges, place them together, and hold them 

 2 or 3 minutes. 8. A desirable cement is 

 made by burning oyster shells, and pul- 

 verizing the lime from them very fine ; 

 then mixing it with white of egg to a 

 thick paste, and applying it to the china 

 or glass, and securing the pieces together 

 until dry. Take 4 pounds of white glue, 

 i)4 pounds of dry white lead, j4 a pound 

 of isinglass, 1 gallon of soft water, 1 

 quart of alcohol, and y 2 a pint of white 

 varnish. Dissolve the glue and isinglass 

 in the water by gentle heat, if preferred ; 

 stir in the lead, put the alcohol in the var- 

 nish, and mix the whole together. 10. 

 A cement that will mend marble, china 

 and ornamental ware is made by taking wa- 

 ter 1 gallon, nice glue 3 pounds, white lead 

 4 ounces, alcohol 1 quart. Mix. Direc- 

 tions — If it is cold weather, warm the 

 bottle until the cement is dissolved ; then 

 with the finger or a brush, rub it on the 

 broken parts (both edges), put together, 

 and retain in their places until dry. 11. 

 A cement withstanding both heat and 

 moisture is simply pure white lead or zinc 

 white, ground in oil, and used very thick. 

 It is excellent for mending broken crock- 

 eryware, but it takes a very long time to 

 harden sufficiently. The best plan is to 

 place the mended object in some store- 

 room, and not to look after it for several 

 weeks, or even months. After that time 

 it will be found so firmly united that, if 

 ever again broken, it will not part on the 

 former fracture. 



CEMENT, Egg.— White of egg, thick- 

 ened with finely-powdered quick-lime. 

 Used to mend earthenware, glass, china, 

 marble, alabaster, spar ornaments, etc. It 

 does not resist moisture. 



CEMENT, for Leather. — To 10 parts, 

 bisulphide carbon and 1 part spirits tur- 

 pentine add enough gutta-percha to make 

 a tough, thickly-flowing liquid. The sur- 

 faces to be joined must be perfectly free 

 from grease, which is accomplished by 

 laying a cloth upon them and apply- 

 ing a hot iron for a time. The coat 

 is appled to both surfaces, and pressure 

 made till the joints are dry. 



CORN CRIBS, Rat-Proof, to Make.— 

 Let the four corner posts be eight inches 

 square, frame the sills which support the 

 floor of the corn cribs into posts, a dis- 

 tance of two feet from the lower end. 

 Before putting the frame together, taper 

 the lower ends of the posts for the dis- 

 tance of two feet, so that at the very 

 base the posts shall only be four inches 

 square. Now, when the frame is set up r , 

 let the posts also stand on tapered rocks. 

 If the crib needs more than these four 

 posts to bear up the corn that will be put. 

 in it, make the legs like the lower portion, 

 of these posts, and set these legs under 

 the sills. Now lay the joists or sleepers 

 on the sills, and put on the floor, making 

 tight, and about three feet from the. 

 ground. Having the door made tight,. 

 keep it shut, and no rats will get into< 

 your crib. 



DEER SKINS, to Dress. — Put the skin; 

 into the liquid while warm, viz. : eight 

 quarts rain water, to one pint soft soap. 

 Warm it. Then punch the hide, or work 

 it with a soft stick and let it lie one day. 

 It is then to be taken out and wrung — 

 rolled between two logs — or even a wring- 

 ing machine will be better. Then stretch 

 it until it is dry, in the sun is best, or by 

 a hot fire. Then oil it thoroughly with 

 any oil convenient. It should then be 

 treated to the same bath of suds (heated 

 quite warm), and lie another day. Then 

 pull it out and dry as before. Any oil 

 will do, but good fresh butter is better 

 than anything else. When the skin is 

 dry rub it with ochre, which will give it a 

 splendi d yellow color. 



FURNITURE, Varnished.— This may 

 be finished so as to look equal to the best 

 French polished wood, in the following 

 manner: Take two ounces of tripoli, 

 powdered; put it into an earthen pot, 

 with just enough water to cover it ; then 

 take a piece of white flannel, lay it over 

 a piece of cork or rubber, and proceed
