At this time that part of North America which borders on the Arctic ocean had never been explored. Only two white men, employees of the Hudson Bay Company, had ever looked upon this ocean from the continent of North America. The first, Samuel Hearne, traveled northward with the Indians in 1770, and reached the mouth of a large river which was named the Coppermine, because the Indians said that large mines of copper were to be found along its banks. The second explorer, Alexander Mackenzie, in 1789 traced to its mouth the river which now bears his name. With the exception of these two river mouths, the entire northern coast of North America was unknown. The map which is to-day covered with names of places, was then a blank. This was the region which Franklin was to explore. Many men would dread such a journey, but Franklin liked it because of the very dangers involved. Dr. John Richardson, midshipmen Robert Hood and George Back, and a seaman, John Hepburn, were selected to go with Franklin on this trip; they were well chosen, for they were worthy companions of the young leader. On May 23, 1819, he and his men sailed on the _Prince of Wales_ for the Arctic land. The voyage was long and stormy; several times it seemed likely that the _Prince of Wales_ would never touch land again, but at the end of three months she anchored off York Factory, on the southern shore of Hudson bay, one of the posts built by the Hudson Bay Company for the purpose of trading in furs with the Indians. The people at York Factory received Franklin and his companions kindly and helped them all they could. They gave Franklin a boat for his journey through the lakes and rivers on his way to the sea. The same sort of boat is still in use in that region and is called a York boat. It is forty feet in length, narrow, light, and sharp at both ends. About ten men can manage it. When on lakes or traveling down streams the men use oars, but when traveling against the current of a river they run alongshore and drag the boat after them. This long and narrow boat is well suited for shooting rapids, through which it is guided by means of long poles. Sometimes the rapids are so swift that they cannot be navigated, and falls are often encountered. Then the cargoes are taken out of the boats and carried around the rapids or falls, and afterward the boats also are carried around. Such a place is called a portage. The officers of the Hudson Bay Company, besides giving Franklin a boat, sent word to other trading posts throughout the country, to look out for him and to help him. The party, having secured boats and stores, started from York Factory to continue their journey. After traveling seven hundred miles, they reached another post called Cumberland House, where Franklin expected to find guides and hunters, but every one refused to undertake a journey so full of peril.
