What type of supplies did buck and his teammates leave skagaway with?

Buck watches apprehensively as they clumsily take down the camp, improperly rolling the tent, and loading up the sleigh unevenly. Two other men from a neighboring camp warn them that the sled is too heavy, but they will not listen. The team cannot move the sled. They are repeatedly whipped by Hal, as Mercedes cries over them. Buck does not like her, but tolerates her pleading pats.

When the sled finally moves,it falls on it's side. Raging at the unfair treatment, Buck leads the team in a run, scattering the belongings even further and running the sled over Hal. Finally taking the advice of those around them, they remove many of the superfluous luxuries, though Mercedes cries over them, and more dogs are added to the team. The journey begins. The new dogs are relatively useless -- Buck can teach them "what not to do," but he can't teach them "what to do."

The tent was rolled into an awkward bundle three times as large as it should have been. The tin dishes were packed away unwashed. Mercedes continually fluttered in the way of her men and kept up an unbroken chattering of remonstrance and advice. When they put a clothes-sack on the front of the sled, she suggested it should go on the back; and when they had put it on the back, and covered it over with a couple of other bundles, she discovered overlooked articles which could abide nowhere else but in that very sack, and they unloaded again.
