Midnight Sun
It was true ; the factor in charge of the embarkation-work was checking out the cargo for each boat . Each scow had its number , and that number was credited to a certain fur-post along the great route to the mouth of the Mackenzie River . The supplies intended for each boat , therefore , went into the proper boats . All the cargo intended for Uncle Dick 's party was marked in black , `` M. S. , '' in courtesy to the name of this boat , the _ Midnight Sun _ , which carried no number at all . `` We 'll not go as heavily loaded as some of the others , '' Uncle Dick explained , `` although it is only courteous that we should take all we can , since transportation is so hard . We need only enough to take us to the mouth of the river and over the Rat Portage to the Yukon . Of course we 'll forget all about our boat when we get below the rapids , but they 'll tow her down alongside the steamer .
