' This invention s a novei-processot tanning"'which may be practiced by unskilleda or *at -a slight-expense and withont the use ofanyparticular machinery; g n In practicing the invention, If" th'qhldes are dry, they are soaked-in clearlw'ater until pliable ;alum is then rubbed," on the flesh side, from 1;.to 2 pounds being used, according gthj'h-idesare soft, the preliminary soaking :to the size of 'the hide. may be omitted and the dry alum rubbed at is then roiled I 'thatcondition tor from 24 th 1'8j'llO11IS. .1 next dissolve from 1 to "5 pounds. of: Terra- 4 allons of hot water,
the liquid, ZXftQIF 'lhlS OOZQ is'eool, the hide is'im mersed'ahd permitted. to remain in the; same-from lftofi-days, according to the size and thickness off-the hide; hen thohide has been subjected to'this bath o'rooze to'rhL .i'suiiioientf period. of time, it'is taken: out and 1 washed in clear-Water until the hair or-t'un is clean, after whielrit is beaten or pressed The-flesh side is then placed in aisha 'ded place until-it, is dry, after which the hair or for" is eomb'ed or brushed until it is finished.
If the hair orffuris t0'be v removed, the hide is pla-ce'din a bathof water and slaked limecr -Woodv ashes and left therein until .th'e'hai'r 'orffur' slips freely. The hide is then put in clear or running Water for from- 6 to l2fhours,- according ,to the thickness andosize of the hide after which it is subjected to the action of the tanning ooze in the manner described.
In treating small hides, such as calf or goatskins, after thetannin has been completed, the, grain side ofthe skin may be Specification of Ltte'rslatent. hpbucation filed March 21,1908. Serial 17034283770.

The above idescribed process produces a leather of great durability and a high finish.
The application of I r calnm to the flesh side of thegreen 'h-ide d riiies from the same J all glu en "..ilvlbl1IIIlIlOlClS andleaves the hide open and porous so that the ooze in which it is subsequently itratethehide deeply and thoroughly. The haie'will be set sufficientlyto prevent its slipping during the subsequent treatment of the-hide, and the Terra Japonieawill contoughleatherfrom which the hair will never shed'nor lose natural softness.
Hating thus described my invention, what 'I'Iclannus.

In testimony that I claim the foregoing as my own, Ilmvohereto affixed my signa- Il ture in the presence of two witnesses.
