In the year 1640, a prolonged session was the cause of many members absenting themselves from their places in the House of Commons. In order to ensure a more general attendance it was then determined that the Speaker should not take the Chair unless there were at least forty members present in the House. This rule still holds good, and to-day, if a quorum of forty is not obtainable before four o'clock, the sitting is suspended until that hour. Should the same difficulty arise after four o'clock, the House is adjourned until the next sitting day.[382] An exception is made in favour of the hour between 8.15 and 9.15, but if a division be taken during that hour in the absence of a quorum, the business in debate must be postponed and the next business brought on. When, too, a message from the Crown is delivered, the House of Commons is held to be "made" even though forty members are not present. On such an occasion the business of the day can be proceeded with so long as no notice is taken of the absence of a quorum. [382] The right of "counting out" the House was not exercised until 1729. On May 19, 1876, the Commons failed to "make the House" for the first time since April 4, 1865. See Irving's "Annals of Our Time," vol. ii. p. 197. It is not the Speaker's (or Chairman's) duty to notice the absence of a quorum, but if his attention is drawn to it by a member he must at once rise in his place and proceed to count the House. There is a well-known story of a prolix member speaking to empty benches in the Commons who referred sarcastically to the packed audience hanging upon his words, and was interrupted by the Speaker, who at once proceeded to "count out" the House, and put an end to the sitting as well as to the member's oration. The Speaker's inability to count the House out of his own accord has occasionally given rise to inconvenient situations. Lord George Gordon once rose and requested permission to read from a book, which was granted. He then proceeded to read the Bible until the House dwindled from upwards of four hundred members to two, namely, the Speaker and Lord George himself, who had the indecency to keep the former in the Chair till the candles were "fairly in the socket."[383] [383] Pearson's "Political Dictionary," pp. 23-4.
