Mass. Gen. Laws ch. 276, § 35: Adjournments of examinations and trials

Section 35. The court or justice may adjourn an examination or trial from time to time, and to the same or a different place in the county. In the meantime, if the defendant is charged with a crime that is not bailable, he shall be committed; otherwise, he may recognize in a sum and with surety or sureties to the satisfaction of the court or justice, or without surety, for his appearance for such examination or trial, or for want of such recognizance he shall be committed. While the defendant remains committed, no adjournment shall exceed thirty days at any one time against the objection of the defendant.
