How far this invention has restored that free circulation of labour, which the preceding statutes had almost entirely taken away, we may learn from the following very judicious observation of Doctor Burn. “It is obvious,” says he, “that there are divers good reasons for requiring certificates with persons coming to settle in any place; namely, that persons residing under them can gain no settlement, neither by apprenticeship, nor by service, nor by giving notice, nor by paying parish rates; that they can settle neither apprentices nor servants; that if they become chargeable, it is certainly known whither to remove them, and the parish shall be paid for the removal, and for their maintenance in the mean time; and that, if they fall sick, and cannot be removed, the parish which gave the certificate must maintain them; none of all which can be without a certificate. Which reasons will hold proportionably for parishes not granting certificates in ordinary cases; for it is far more than an equal chance, but that they will have the certificated persons again, and in a worse condition.” The moral of this observation seems to be, that certificates ought always to be required by the parish where any poor man comes to reside, and that they ought very seldom to be granted by that which he purposes to leave. “There is somewhat of hardship in this matter of certificates,” says the same very intelligent author, in his History of the Poor Laws, “by putting it in the power of a parish officer to imprison a man as it were for life, however inconvenient it may be for him to continue at that place where he has had the misfortune to acquire what is called a settlement, or whatever advantage he may propose himself by living elsewhere.” Though a certificate carries along with it no testimonial of good behaviour, and certifies nothing but that the person belongs to the parish to which he really does belong, it is altogether discretionary in the parish officers either to grant or to refuse it. A mandamus was once moved for, says Doctor Burn, to compel the church-wardens and overseers to sign a certificate; but the Court of King’s Bench rejected the motion as a very strange attempt.
