If the Commissioner is unable to obtain from the taxpayer adequate and reliable information upon which to base such assessment, the assessment may be made upon the basis of the best information available and, subject to the provisions hereinafter made, such assessment shall be deemed correct.
Provided, the taxpayer may request the Commissioner at any time within 30 days of notice of such proposed assessment for a written statement, or transcript, of the information and the evidence upon which the proposed assessment is based, and the Commissioner of Agriculture shall furnish such statement, or transcript, to the taxpayer. Provided, further, after request by the taxpayer for such written statement, or transcript, the taxpayer shall have 30 days after the receipt of the same from the Commissioner of Agriculture to apply in writing for such hearing, explaining in detail his objections to such proposed assessment. If no request for such hearing is so made, such proposed assessment shall be final and conclusive.
