laid together, pressed slightly, and suffered to dry, be as firmly united as 

 other parts of the substance. 



:^lastic Glue. If glue or gelatine is incorporated with about one- 

 quarter of its weight of glycerine, it loses its brittleness, and becomes 

 useful for many purposes for which it is otherwise unfit, such as dressing 

 leather, giving elasticity to parchment or enameled paper, and for book- 

 binding. 



Mucilage, i. Put three ounces of gum arabic in an earthenware 

 vessel containing half a pint of cold water. If the liquid is occasionally 

 stirred, the gum in twenty-four hours will be dissolved and the mixture 

 ready for use. Cloves will keep it from moulding. 



2. Fine clean glue, one pound; gum arabic, ten ounces; water, one 

 quart; melt by heat in a glue kettle or water-bath; when entirely melted, 

 add slowly ten ounces strong nitric acid, and set off to cool. Then bot- 

 tle, adding a couple of cloves to each bottle. 



WAGON TIRES AND FENCE POSTS. 



Wagon Tires Kept From l/oosening. If this plan is careful- 

 ly followed, tires on wagons will not get loose and require resetting. 

 Use a tin-pan long and narrow, and deep and fill with oil, setting it on an 

 oil stove. I,et the oil come to a boiling heat, and then placing the stove 

 and pan near a post or studding, hang the wheel on a peg put in the 

 post or studding, so that the felloe of the wheel will run in the oil. 

 Thoroughly soak each felloe an hour. The timber should be dry, as 

 green timber will not take oil. Care should be taken that the oil is not 

 made hotter than a boiling heat or the timber will be burned. Timber 

 filled with oil is not susceptible of injury by water, and is rendered 

 much more durable by this process. 



Fence Posts. Any sort of timber, when employed for fence-posts 

 will be more than twice as durable if allowed to become well seasoned 

 before being set in the ground! The durability of seasoned posts may 

 be promoted, so as to make them last for an age, by the application of a 

 heavy coat of coal-tar to the portion buried in the earth, and a few in- 

 ches above the surface of the tar. The ground-end may be put in hot 

 tar and let boil for fifteen minutes. When cool, cover with coal-tar 

 thickened with ground slate or ground brick. The boiling causes the 

 pores to absorb tar. The coating prevents the action of moisture. But 

 such a treatment of green posts would do but very little good and per- 

 haps mischief. The better way is to season the post well before setting
