office was 7,000,000, weighing nearly 40 tons ; or, if the blank enumeration 

 books and other forms be included, upwards of 52 tons. The schedule 

 was to be filled up on the night- named. No one present on that night 

 was to be omitted, and no person absent was to be included, except police- 

 men and others on night duty ; and miners, potters, and other work- 

 people usually engaged at their labor during the night, and regularly 

 returning home in the morning ; persons travelling were enumerated at 

 the hotels or houses at which they might stop 011 the following morning. 



At the same time that these schedules were distributed, the enumerators 

 delivered forms for collecting information respecting places of worship, 

 scholastic establishments, and miscellaneous institutions, but it was 

 optional with the respective parties to decline making these returns if 

 they thought proper. 



When a house was uninhabited, or in process of building, the enumera- 

 tors made a note of such a case upon the schedule last collected, by which, 

 means the unoccupied houses, and houses in course of erection, were 

 enumerated. The number of inhabited houses was indicated by the 

 number of householders' schedules rilled up. 



Having collected all the schedules, and copied them into books prepared 

 after a certain form, the enumerators summed the various total* in their 

 respective districts. The totals thus obtained expressed the number of 

 persons who were inmates of dwelling-houses on the night of the census, 

 with the special addition of certain classes on night duty ; but several 

 classes had yet to be enumerated viz. : the persons who, on the night 

 named, slept or abode either in barges, boats, or other small vessels remain- 

 ing stationary on canals or other navigable streams, in barns, sheds, and the 

 like, and in tents or in the open air. The number of these in each district 

 was estimated by the respective enumerators ; the estimate, however, was 

 not to include people in coasting or other sea-going vessels, as they would 

 be dealt with by other means yet to be described. 



The enumerators were allowed one week for the transcription of the 

 contents of the householders' schedules into the enumeration book, and 

 for the completion of the various summaries and estimates. The schedules 

 and book, together with the retuins relating to schools and places of 

 worship, were then forwarded to the respective registrars, and the duties of 

 the 38,7-iO enumerators terminated. The census returns were now in the 

 hands of 3,2 20 registrars, or dividers of districts. 



The registrars immediately commenced a careful and systematic exami- 

 nation and revision of the documents described, directing their attention, 

 according to instructions, to nine specially defiued points in respect to 

 them. They then prepared a summary of the statements of the enume- 

 rators in their respective districts, and transmitted them, together with the 

 enumeration books, to the superintendent-registrar, for a further revision, 

 by that officer, forwarding the householders' schedules and returns for 

 places of worship and schools direct to the census office. T \Vith the 

 completion of these duties, for which a for'tnight was allowed, the
