Even the arrangement of seats in the House is not without its bearing upon political life; and although a small matter, it affords another illustration of the principle that an institution which, instead of being deliberately planned, is evolved slowly, will develop in harmony with its environment, or force its environment into harmony with itself. The front bench at the upper end of the aisle, close at the right hand of the Speaker, is called the Treasury Bench, and is reserved for the ministers; the corresponding bench on the other side being occupied by the former ministers of the party now in Opposition. Behind these two benches sit for the most part men whose fidelity to their respective parties is undoubted, members whose allegiance is less absolute generally preferring seats below the gangway on either side. Of course, on a crowded night members cannot always find seats that express their exact sentiments. Still, the arrangement is fairly well preserved, especially in the case of prominent men, with whom it is sometimes a matter of no little consideration.[251:1] Any group that desires to emphasise its freedom from regular party control always sits below the gangway. The Fourth Party, for example, sat in 1884 below the gangway on the Opposition side, the Labour Party has sat there since the election of 1906, and the same position is occupied by the Irish Nationalists under every ministry; while the Liberal Unionists at the time of their breach with Mr. Gladstone over his first Home Rule Bill took up their seats below the gangway on the government side. The House at a great debate resembles a martial array, with the leaders face to face in the van, supported by their troops in ranks behind them. The minister leans over the table, and points in indignation or in scorn at the "honourable gentlemen opposite." All this expresses the idea of party government, and lends a dramatic effect to parliamentary warfare. [Sidenote: Mode of Treating the Subject of Procedure.]
