“In the Chinese government,” observes Dr. Morrison, “there appears great regularity and system. Every district has its appropriate officers, every street its constable, and every ten houses their tything man. Thus they have all the requisite means of ascertaining the population with considerable accuracy. Every family is required to have a board always hanging up in the house, and ready for the inspection of authorized officers, on which the names of all persons, men, women, and children, in the house are inscribed. This board is called _mun-pai_ or ‘door-tablet,’ because when there are women and children within, the officers are expected to take the account from the board at the door. Were all the inmates of a family faithfully inserted, the amount of the population would, of course, be ascertained with great accuracy. But it is said that names are sometimes omitted through neglect or design; others think that the account of persons given in is generally correct.” The door-tablets are sometimes pasted on the door, thus serving as a kind of door-plate; in these cases correctness of enumeration is readily secured, for the neighbors are likely to know if the record is below the truth, and the householder is not likely to exaggerate the taxable inmates under his roof. I have read these _mun-pai_ on the doors of a long row of houses; they were printed blanks filled in, and then pasted outside for the _pao-kiah_ or tithing man to examine. Both Dr. Morrison and his son, than whom no one has had better opportunities to know the true state of the case, or been more desirous of dealing fairly with the Chinese, regarded the censuses given in the _General Statistics_ as more trustworthy than any other documents available. ~EVIDENCES IN FAVOR OF THE CENSUS.~
