The Commissioner of Agriculture and Industries shall be entitled to deduct three percent of all sums remitted to the Department of Agriculture and Industries under this article to defray expenses incident to collection and administration thereof. The amount thus deducted by the commissioner for expenses incident to the administration of this article shall be paid into the State Treasury to the credit of the Agricultural Fund.
