Upon a trial for the violation of any of the provisions of this chapter, it is not necessary to prove the existence of any lottery in which any lottery ticket purports to have been issued, or to prove the actual signing of any such ticket or share, or pretended ticket or share, of any pretended lottery, nor that any lottery ticket, share, or interest was signed or issued by the authority of any manager, or of any person assuming to have authority as manager; but in all cases proof of the sale, furnishing, bartering, or procuring of any ticket, share, or interest therein, or of any instrument purporting to be a ticket, or part or share of any such ticket, is
evidence that such share or interest was signed and issued according to the purport thereof.
