these are not measured with it.  [If they are] less than this, they are to be measured with it.  Now, why [should they  not be measured with it]? Let them  [at least], be [treated as if they had been] consecrated separately!  And if you will suggest [that] since they do not contain a [full] beth kor they cannot become consecrated,  surely it has been taught: Why is it expressly said, [the] field!  — Because, since it was said, the sowing of a homer of barley shall be valued at fifty shekels of silver,  one might infer only a similar consecration;  whence [however, may it be inferred that] a lethek,  half a lethek, a se'ah,  a tarkab  and half a tarkab are also included [in this law]? [For this reason] it has been expressly stated, [the] field, [which implies consecration in any manner.  [Why, then, could not the clefts or the rocks be consecrated separately?] R. Ukba b. Hama replied: Here is a case of clefts full of water in which no sowing is possible. This may also be proved by deduction, for [the clefts] were mentioned in an analogous position to that of rocks.  This proves it. If so,  even [if they are] less than [ten handbreadths they should] also [not be measured with the field]! These  are called small clefts of the earth [and] the spines of the earth. What [is the law] here?  — R. Papa said: Even though they are not full of water. What is the reason? — A person does not wish to invest his money in one plot which has the appearance of two or three plots. Rabina raised an objection: Surely, [the clefts] were mentioned in an analogous position to that of the rocks; as the rocks [are excluded] because they are unsuitable for sowing so these also [should be excluded only] when unsuitable for sowing? — The similarity to rocks refers to [the case where they are] less  than [ten handbreadths]. R. Isaac said: The rocks  which have been spoken of  [must not together cover more than an] area [requiring] four kab [of seed].  R. 'Ukba b. Hama said: And this, only when they  are distributed over [an area which requires not less than] five kab [of seed].  R. Hiyya b. Abba said in the name of R. Johanan: This, only when they  are distributed over the greater part of the field. R. Hiyya b. Abba inquired: [What is the law if] the greater part of them  is [scattered] over its  smaller part, and the smaller part of them  over its  greater part? — The matter is undecided? R. Jeremiah inquired:
