the desires of Prime Minister William Lyon Mackenzie King who, while speaking in the House of Commons of Canada in May 1922, argued in favour of placing the memorial at Vimy Ridge. King's position received the unanimous support of the House and, in the end, the commission selected Vimy Ridge as the preferred site. The government announced its desire to acquire a more considerable tract of land along the ridge after the commission selected Vimy Ridge as the preferred location for Allward's design. In the interval between the 1st and 2nd session of the 14th Canadian Parliament, Speaker of the House of Commons of Canada Rodolphe Lemieux went to France to negotiate the acquisition of more land. On 5 December 1922, Lemieux concluded an agreement with France in which France granted Canada "freely and for all time" the use of of land on Vimy Ridge, inclusive of Hill 145, in recognition of Canada's war effort. The only condition placed on the donation was that Canada use the land to erect a monument commemorating Canadian soldiers killed during the First World War and assume the responsibility for the maintenance of the memorial and the surrounding battlefield park. Memorial construction Following the competition, Allward spent the remainder of 1921 and the spring of 1922 preparing for his move to Europe. After selling his home and studio, Allward finally departed for Belgium on 6 June 1922 and spent several months seeking a suitable studio in Belgium and then Paris, though he eventually set up a studio in London. Allward had initially hoped to use white marble for the memorial's facing stone, but Percy Nobbs suggested this would be a mistake because marble was unlikely to weather well in northern France and the memorial would have a "ghost like" appearance. Allward undertook a tour of almost two years to find stone of the right colour, texture, and luminosity. He found it in the ruins of Diocletian's Palace at Split, Croatia; he observed that the palace had not weathered over the years, which Allward took as evidence of the stone's durability. His choice—Seget limestone—came from an ancient Roman quarry located near Seget, Croatia. The difficulties with the quarrying process, coupled with complicated transportation logistics, delayed delivery of the limestone and thus construction of the memorial. The first shipment did not arrive at the site until 1927, and the larger blocks, intended for the human figures,
