¶1OPINION.
¶2The determination of the Commissioner must be approved for the reason that the Board has no evidence whatever upon which it can base any findings of fact. Taxpayer’s petition contains the following allegation:
The determination of the tax contained in the said deficiency letter is based upon the following errors:
Undervaluation of certain lots as of March 1, 1913.
The facts upon which the taxpayer relies as to the basis of his appeal are as follows:
That the lots in question were actually worth at least $10,000.00, as of March 1, 1913.
¶3*1293The only evidence before the Board is the depositions of two alleged real estate experts, who estimated that at some time about March 1, 1913, the value of certain lots situated outside of the city limits of Miami, known as block 69, was approximately $10,000. We have no evidence that these lots belonged to the taxpayer, or, if they did, what he paid for them, or for what amount or when he sold them, or that the deficiency determined by the Commissioner was based in whole or in part upon a gain derived from the sale or other disposition of such lots or of any property belonging to the taxpayer, and we can not, therefore, determine the gain or loss. Appeal of Anniston City Land Co., 2 B. T. A. 526.
