Chap. 421.        AN  ACT RELATIVE TO THE AUTHORITY OF THE METROPOLITAN DISTRICT COMMISSION OVER THE WATERS OF BOSTON HARBOR.
Whereas,    The deferred operation of this act would tend to defeat its purpose, which is to provide for immediate effective law enforcement in Boston harbor, therefore it is hereby declared to be an emergency law, necessary for the immediate preservation of the public safety.___________________________________________
Be it enacted, etc., as follows:
Chapter 92 of the General Laws is hereby amended by striking out section 61,  as amended by section 2 of chapter 162 of the acts of 1954, and inserting in place thereof the following section:-
Section 61.    The police appointed or employed by the commission, except special police officers,   shall have within the metropolitan parks district, and within the towns outside said district wherein any  of the  property  of the metropolitan water and sewerage districts is situated, within the waters of Boston harbor, including the coastline and coastal waters of the following cities and towns: Boston,   Braintree,   Cambridge,   Chelsea,   Cohasset,   Everett, Hingham,   Hull,   Lynn,   Marblehead,   Milton,   Nahant,   Quincy, Revere, Saugus, Somerville, Swampscott, Weymouth, and Winthrop, all the powers of police officers and constables of towns of this commonwealth,  except the power of serving and executing civil process,  and may carry within the commonwealth such weapons as  the said  commission  shall  authorize.
