Whenever the school committee of any city or town shall find that it is more convenient or expedient for any child residing in the city or town to attend school in an adjoining city or town, the committee may arrange with the school authorities of the city or town for the attendance of the child at their schools, and may pay for the tuition out of the city or town appropriation for public schools. The amount paid shall be used for school purposes only.
