Regulation 4 Making of returns
Any person required by section 5 of the Act (weekly returns of purchases of British corn) to make a return shall, save where he and the Authority have agreed that he shall do so in some other manner, either—
do so in writing, and sign it, and then post it by first class post, or
complete it in such a way that it is capable of being easily read after transmission by facsimile machine, and then send it by means of such a machine,
to the Authority on each Friday (or, if that Friday is a public holiday, the next working day) occurring next after a period for which he is required to make a return.
A return shall contain the information specified in Schedule 2 to these Regulations, and shall relate to the period of seven days (starting on a Friday) most recently preceding the day on which it is required to be posted or sent to the Authority.
A separate return shall be made for each of the prescribed areas from which the person required to make the return purchased British corn by wholesale from the grower, or if no such purchase was made during the seven-day period in question a return shall be made stating that fact.
