criticised it as "a war more unjust in its origin, a war more calculated in its progress to cover this country with permanent disgrace". His hostility to opium stemmed from the effects of opium upon his sister Helen. Before 1841, Gladstone was reluctant to join the Peel government because of the First Opium War, which Palmerston had brought on. Minister under Peel (1841–1846) Gladstone was re-elected in 1841. In the second ministry of Robert Peel, he served as President of the Board of Trade (1843–1845). Gladstone was responsible for the Railways Act 1844, regarded by historians as the birth of the regulatory state, of network industry regulation, of rate of return regulation, and telegraph regulation. Examples of its foresight are the clauses empowering government to take control of railway in time of war, the concept of Parliamentary trains, limited in cost to a penny a mile, of universal service, and of control of the recently invented electric telegraph which ran alongside railway lines. Railways were the largest investment (as a percentage of GNP) in human history and this Bill the most heavily lobbied in Parliamentary history. Gladstone succeeded in guiding the Act through Parliament at the height of the railway bubble. Gladstone became concerned with the situation of "coal whippers". These were the men who worked on London docks, "whipping" in baskets from ships to barges or wharves all incoming coal from the sea. They were called up and relieved through public houses, so a man could not get this job unless he had the favourable opinion of the publican, who looked most favourably upon those who drank. The man's name was written down and the "score" followed. Publicans issued employment solely on the capacity of the man to pay, and men were often drunk when they left the pub to work. They spent their savings on drink to secure the favourable opinion of publicans and further employment. Gladstone initiated the Coal Vendors Act 1843, which set up a central office for employment. When that Act expired in 1856, a Select Committee was appointed by the Lords in 1857 to look into the question. Gladstone gave evidence to the committee, stating: "I approached the subject in the first instance as I think everyone in Parliament of necessity did, with the strongest possible prejudice against the proposal [to interfere]; but the facts stated were of so extraordinary and deplorable a character,
