They were first surprised to see a couple of 

 men move a large tree, seemingly with great 

 ease to themselves, only by putting, each of

 their end of the pole, the tree rolled along. 

 Sometimes they placed a block under the pole, 

 close to the tree, then depressed the end they 

 held, and that really lifted up the heavy tim- 

 ber log. Harry soon saw, that one thousand 

 men, if they had been there, could only have 

 stood still looking at each other ; and that as 

 many as could conveniently have taken hold of 

 the tree, could not have lifted it as those two 

 men did by means of their poles.
