INTRODUCTORY OR HISTORICAL NOTE. 



On the 3d of March 1830 the Legislature of Massachusetts passed 

 a Resolve, authorizing and requesting the Governor with the advice 

 of the Council, "to appoint a Surveyor well skilled in astronomy and 

 in the art of surveying upon trigonometrical principles — to make a 

 general Survey of the Commonwealth, and from such astronomical ob- 

 servations and calculations as may be made, to project an accurate 

 skeleton plan of the State, which shall exhibit the external lines there-

 the advancement of domestic prosperity, would be discovered, and the 

 possession and advantages of them given to the public. I am assur- 

 ed that much has already been gratuitously done, by some eminent 

 professors in our colleges, towards the accomplishment of such a work, 

 and that, at a little expense, it might be completed, and the fruits of 

 their generous labors thus far, be secured to the State. This, howev- 

 er, will require the interposition of your authority in increasing the 

 present appropriation, and permitting an application of it, so far as 

 may be necessary, in the exercise of a sound discretion, to the end pro- 

 posed." 



In conformity with these suggestions, the Legislature, on the 5th of 

 June, 1830, "Resolved, That his Excellency the Governor, by and with
