lowered its quality and it was far more susceptible to the dry rot that was one of the navy's more implacable foes. A frigate made of colonial wood tended to have only half the life span of a Baltic ship. Because of timber's great importance, in 1820 a committee of the House of Lords was formed to review the state of the timber trade. Led by Lord Lansdowne the committee strongly supported the reduction of the duties. This has been viewed as one of the first successes of free trade ideology in Britain. The duties were not eliminated, but they were brought to a level that left Baltic wood competitive with that from Canada. These reductions were a rare example of laissez-faire in an era still almost totally committed to mercantilism. The post-war era also saw a great unwillingness to enforce the duties that were in place. Rampant smuggling of timber into and out of Norway was mostly ignored, as were the illegal exports of bullion to fund the trade. In 1824 the duties were further lowered when Britain began to sign reciprocity treaties with other powers. Out of the first ten bilateral trade treaties signed, seven of them were with Baltic nations covering all the major timber exporters except for Russia. These quick reversals of Baltic trade policy in an era before free trade was paramount can almost certainly be attributed to the navy's unwillingness to become reliant on Canadian timber now that trade with the Baltic had been unquestionably secured. In seeking the exploit of further timber resources was one of the reasons of the First and the Second Anglo-Burmese War (1824–1826 and 1852, respectively). Burma had to cede Assam, Manipur, Rakhine (Arakan) and Tanintharyi (Tenessarim) and later the remaining coastal provinces: Ayeyarwady, Yangon and Bago. During the following years timber was harvested introducing new techniques. The British cut the bark off the trees and left them to dry before felling them roughly four years later with the use of elephants. Dry wood was easier to fell and floated in water and therefore the river Irrawady was used for transporting the wood to the saw mills near Rangoon. Other sources were the wood from Australia which included Jarrah and Karri wood. Some streets in London are still paved with Karri wood from the southern parts of Western Australia. But Jarrah wood is more resistant to water and therefore
