But by far the most systematic effort to restrain extravagance at elections is found in the provisions that prescribe on the one hand the objects of expenditure, and on the other its total amount. A schedule to the Act of 1883 enumerates the objects for which expenses may be legally incurred, and the first part of the schedule deals with the persons who may be employed. These are: one election agent;[227:1] a polling agent to watch the voting at each polling station; and clerks and messengers in proportion to population, the allowance being somewhat more liberal in counties than in boroughs on account of the greater area of the constituency. The act provides that, except as authorised by this schedule, no person shall be employed for pay;[227:2] and that no paid employee shall vote.[227:3] It may be noticed that among the list of persons who can be employed, canvassers are not mentioned, and hence the use of paid canvassers is illegal.[227:4] Now, as canvassing, that is the personal solicitation of votes, is by far the most effective part of the work done at an election, each candidate is always assisted by an army of volunteers. Wherever possible he is also helped by the agents of other constituencies, or of distinct associations, who, not being paid by him, and in fact, receiving no additional pay for their services on this occasion, are not within the prohibition of the law. [Sidenote: Other Expenses.] The other expenditures authorised by the schedule are printing, advertising, stationery, postage, and the like; public meetings; one committee room for every five hundred electors;[227:5] and miscellaneous expenses not exceeding two hundred pounds for matters not otherwise illegal. The candidate is also allowed to incur personal expenses for travelling and hotel bills;[227:6] and, finally, there are the charges of the returning officer for the cost of erecting polling booths, the payment of persons on duty thereat, and the other expenses attending the election.[227:7] These last charges are divided between the candidates and they are by no means small, as may be seen from the fact that at the general election of 1900 they amounted, for the whole United Kingdom, to £150,278 10_s._ 11_d._, or nearly one fifth of the whole expense incurred.[228:1] The National Liberal Federation has, indeed, repeatedly urged in its programme that such charges ought to be defrayed by the state, instead of being a burden upon the candidates.
