We have every reason to be satisfied with the manner in which 

 we have hitherto been aided in the study of our task, and with 

 which our instructions have been carried out , and if thought desir- 

 able, are prepared to enlarge the scale of operations upon the ground 

 in the spring with entire confidence, based upon the experience we 

 have now had, in the ability and zeal with which we shall be sus- 

 tained, not only by the gentlemen whom we have named, but by all 

 who are engaged in the service of your board.
