the surface a fine "tooth" to take hold of the chalk. If adding the 

 lamp-black and emery makes it too thick, thin with alcohol. Do not 

 let this stand in an open can as it will soon evaporate. This is good for 

 slating the inside covers of children's school books, making them equal 

 to slates. The surface can be written on with a slate-pencil and erased 

 the same as from an ordinary slate. 



Chimney on Fire. Those who burn wood find that the sides of 

 their chimneys are often covered with soot. This is almost pure carbon 

 and when ignited it forms a very fierce fire. The chimney often takes 

 fire during very dry times and endangers the building. 



To extinguish the fire, close all the doors and windows and throw a 

 a few handfuls of salt in the stove or fire-place. Salt in burning gives 

 off a gas, charged with chlorine, in which no fire can burn. Remember 

 the salt must be put on a fire, to generate this gas; therefore do not put 

 out your fire in the stove or grate, instead of putting it out, put on the 

 salt and open the draughts.

To Keep the Ice-Eox Sweet. Keep a small dish of charcoal on 

 one of the upper shelves of the refrigerator, as it is an excellent absorb- 

 ent of odors. It should be changed every few days. 



To Keep Sweet Potatoes. The chief requisite in keeping dur- 

 ing the winter, sweet potatoes, is to place them where they will be per- 

 fectly dry and not come in contact with each other. To accomplish 

 this pack in chaif , placing the tubers in barrels or boxes. Place these 

 boxes in the attic over the kitchen. There they will remain dry. If 

 chaff is not handy they can be packed in dry sand, or, if neither sand 

 nor chaff is available, wrap each potato in two or three thicknesses of 

 newspaper and place in barrels or boxes perfectly free from moisture. 

 Treated thus they will keep perfectly until spring. If no atttic is to be 

 had, any dry well- ventilated room that does not freeze will answer.

 drams of cut isinglass in two ounces of water for twentj'-four hours; boil 

 down to one ounce, add one ounce of spirit of wine and strain through 

 linen. Mix this while hot, with a solution of one dram mastic in one 

 ounce of alcohol, and mix thoroughly with half a dram of powdered 

 p'lim ammonia.
