order as scraping off the hair of the hide. Said R. Hyya b. Abba: R. Ashi told me three things in the name of R. Joshua b. Levi: Sawing rafters on the Sabbath (that they may be equal in size and pointed) makes one liable the same as "cutting." Daubing a plaster on a piece of cloth makes one liable the same as "scraping hair off." Smoothing a stone makes one culpable of "hammering." R. Simeon b. Kisma in the name of R. Simeon b. Lakish, said: Painting pictures on vessels or blowing out glassware makes one culpable the same as hammering. R. Jehudah said: Removing a border from cloth also makes one as culpable as hammering; but only in case one is particular about having the border remain on his cloth.
"Writing two letters." The rabbis taught: "If one wrote one large letter instead of two small ones, he is not guilty of any transgression; but to erase a large letter, in the place of which two small letters can be written, makes one liable for a sin-offering (for the erasing is done with the intent to write, and two small letters are evidently needed).

"Building, demolishing," etc. Both Rabba and R. Zera said: All work which is done in the last stages is considered the same as hammering (which is generally the finishing work).
"These are the principal acts of labor." "These," to exclude a derivation of the same kind as the principal when it is done with the principal together, and as to which R. Eliezer makes one liable for the derivation also.
"Less one," to exclude the extension of the warp or the woof, which R. Jehudah added to the principal acts; but the rabbis said: Extending the warp is included in warping and extending the woof is included in weaving.
Mishna III.: And there is also another rule which was laid down: Whosoever carries out on the Sabbath such things as are fit and proper to be stored and in such a quantity as is usually stored, is liable; but whatever is not fit and proper to be stored, nor in such a quantity as is generally stored, only he who would store this is liable (because the storing shows that for him it is valuable).
Gemara: "Whatever is not fit and proper." Said R. Elazar: The latter part of the Mishna is not in accordance with R. Simeon b. Elazar, who said in the following Boraitha: "There is a rule that all which is not fit and proper to be stored nor in
