Sts. c. 100, § 12, forbidding licensees to place or maintain screens, blinds, curtains, etc., in such a way as to interfere with a view of the business conducted upon the premises, apply to licensees of the sixth class as well as to all other licensees; and it is provided by St. 1882, c. 259, that the placing or maintaining of any such obstructions shall of itself make the license void. See Commonwealth v. Sawtelle, 150 Mass. 320 ; Commonwealth v. McDonnough, 150 Mass. 504.

8. The evidence that the officers called the defendant’s attention to the condition of things in the back shop, and that he made no reply, was competent.
