1. Dwelling houses and number in order of visitation.
The several columns are to be filled as follows:
1. Under heading 1, entitled "Dwelling houses numbered in the order of visitation," insert the number of dwelling houses occupied by free inhabitants, as they are visited. The first house visited to be numbered 1; the second visited, 2; the third one visited, 3; and so on to the last house visited in the subdivision. By a dwelling house is meant a separate inhabited tenement, containing one or more families under one roof. Where several tenements are in one block, with walls either of brick or wood to divide them, having separate entrances, they are each to be numbered as separate houses; but where not so divided, they are to be numbered as one house.
If a house is used partly for a store, shop, or for other purposes, and partly for a dwelling house, it is to be numbered as a dwelling house. Hotels, poorhouses, garrisons, hospitals, asylums, jails, penitentiaries, and other similar institutions, are each to be numbered as a dwelling house; where the house is of a public nature, as above, write perpendicularly under the number, in said column, the name or description, as "hotel," "poorhouse," etc.
