Whatever the size of the county it returned two members elected by freeholders, and the cost of a county election was enormous. Some of the boroughs, especially in Cornwall, were tiny villages. Eighteen members were returned from such boroughs in that part of Cornwall which now returns one member for the Liskeard Division. The fields of Old Sarum belonged to seven electors and returned two members. As there was no habitation whatever in this "borough" of Old Sarum, a tent was put up for the convenience of the returning officer at election times. No general law decided the borough franchise. Local custom and various political and personal considerations settled who should vote for members of Parliament. Places like Westminster and Preston had practically manhood suffrage. In most of the "corporation boroughs" the franchise was restricted exclusively to freemen of the borough, and to the self-elected non-resident persons who composed the governing body before the Municipal Corporation Act of 1835. A small number of rich and powerful men really worked nearly all the elections. Seats were openly bought and sold, and a candidate had either to find a patron who would provide him with a seat, or, failing a patron, to purchase a seat himself. Fox first entered Parliament for the pocket borough of Midhurst, and Sir George Trevelyan has described how it took place. Midhurst was selected by the father of Charles James Fox as "the most comfortable of constituencies from the point of view of a representative; for the right of election rested in a few small holdings, on which no human being resided, distinguished among the pastures and the stubble that surrounded them by a large stone set up on end in the middle of each portion. These burbage tenures, as they were called, had all been bought up by a single proprietor, Viscount Montagu, who when an election was in prospect, assigned a few of them to his servants, with instructions to nominate the members and then make back the property to their employer. This ceremony was performed in March, 1768, and the steward of the estate, who acted as the returning officer, declared that Charles James Fox had been duly chosen as one of the burgesses for Midhurst, at a time when that young gentleman was still amusing himself in Italy." Three years earlier Burke had entered Parliament as a nominee of Lord Rockingham's. Gibbon sat in the House for some years under patronage. Gladstone first became a member by presentation to a pocket borough, and later spoke in praise of this method of bringing young men of promise into Parliament. John Wilson Croker estimated that of six hundred and fifty-eight members of the House of Commons at the end of the eighteenth century, two hundred and seventy-six were returned by patrons. Men of more independence of mind who could afford to buy seats did so, and many of the reformers--including Burdett, Romilly and Hume--thus sat in the House.
