Gotton-sc,d oil, purified as it is when sold for sweet oil, is an excellent butt an expensive oil for leather. Puro olive and castor oil possess the qualities yr,Yuisilo for preserving leather and keeping it soft, but their cost precludes their general use. Castor oil is the best. Fish oil is used moro than any other and to its use may be attributed much If the poor wearing qualities Of the leather now in the market. By an i'm ,;%:vci process of manufacture fish oils are dcodcrized so thoroughly that their presence can no. bo detected. They pen ,.l.ate moro readily than either animal or vegetable oils, but they do not incor- purAte themselves with the fiber. They ! of 2 light nature they are easily drawn out by heat or moisture. They impar1 a soft condition to the leather " ncn 1t is UcW, As much SD If lioG more than do the animal oils. and because of that they arc nuGcondemncd. If used freely in connec ton with hard grease they become ran 'jl, and impart an odor which is TO t.incd as long as there is any grease il the leather.
 Mineral oils are being introduced quito freely, and as they are thorough, ,lrodorized they find eady purchasers These oils are tho worst possibl, that can bc put into leather They havc wonderful penetrating properties, but they are heating, ant their volatile properties deprive then | Cf the permancncy SO necessary TOT tn preservation of the leather. They d not take kindly to other oils or greases and are easily cut by water. While tn natural heat from the feet will caus evaporation, particularly if the leatho is moist, they do not become rancid, hu they are moro injurious to the fiber tha even the most rancid animal oil.
