Early every morning a van calls to take his brief bag up to the Parliament House, where his papers are trustingly displayed in his box in the public … - Hugh Macmillan, Baron Macmillan

The promoters of every private bill have to satisfy the [Parliamentary] Committee that their proposals are sufficiently beneficial to the public to justify the Committee in entrusting them with the special powers necessary to carry them out; it is only on this condition that private rights and interests can be required to give way to public necessity. The task of the Committee is to examine the proposals from this point of view and for this purpose to hear the arguments and evidence both of the promoters and of thhe opponents, being specially vigilant to see that justice is done by way of compensation and protection to those who may be called upon to make sacrifices for the public benefit. The range of the subjects which may come before Parliament by way of private bill is immensely varied, including such matters as the construction of railways, the building of harbours and bridges, the extension of city boundaries, the development of water power and electricity, the provision of water supplies, and the alteration of the constitution and objects of charitable and educational institutions.

The wide experience to be gained at the Scots Bar has its advantages. It does not enable one to become such an expert in any single department as the English specialist... but it tends to a sound knowledge of the legal principles common to all branches of the law. The Scottish Judges have always been more interested in principle than in precedent and the Bar have conformed to this lead. In the House of Lords this feature of Scottish advocacy has been often remarked and admired.

During the long interval which elapsed before the revival and reconstitution of the Secretary-ship in 1885, `the Lord Advocate of the day was really Minister for Scotland. The technical right to control Scottish affairs in their various departments no doubt belonged to the various Ministers of the Crown; but so little was known in London about Scotland and the country was in so distrubed and backward a condition that responsibility was easily devolved upon the only man who knew or cared much about the subject.'
