The allegations in the statement of claim are somewhat ambiguous, but the main facts are clear enough. The plaintiff delivered his eggs to an agent of the board, who credited him with the amount which the eggs would realize if sold at the current prices fixed by the board at which its eggs might be sold less a deduction of one penny per dozen called a "pool deduction." The amount was no part of the proceeds of the commodity vested in the board: it was a payment or advance on account of the payment payable to the plaintiff under the provisions of sec. 23 and was warranted by sec. 24 (3) of the Act. But it was not computed under the provisions of sec. 23, for the net proceeds of the commodity could only be computed at the end of the period of time prescribed in accordance with the section, that is, as already mentioned, the Saturday preceding the first Monday in the month of July 1938. The deduction, which was accounted for in cash to the board, was retained, according to the board's statements, for the stabilization of prices in the common interest. It was used for the expenses incurred by the board, for losses incurred in the operations of the board and so forth. The board's pool account of the 1937-1938 pool, which terminated on 2nd July 1938, was published in December 1938 and shows the income from the pool contributions amounted in round figures to £67,743. Expenditure totalled £42,756, and the net surplus of the pool was £24,987. The board, in its report, also of December 1938, announced that "a further and final advance of one-third of a penny per dozen would be made to all contributors to the 1937-1938 pool." Some small balance, we were informed, was still retained, but it does not appear from the facts stated whether that balance is retained by the board or transferred to the reserve fund mentioned in sec. 18 (1) (i). But it is admitted that the one-third of a penny per dozen was not calculated with reference to the proceeds of all eggs of the same quality or standard vested in the board during the prescribed period.
