226 BOARD OF AGRICULTURE. 



with that vicinity able to point out the locality. We can only 

 refer to our authority for the statement : viz., to Jackson's Second 

 Annual Report on the Geology of the Public Lands, pages 29, 30, 

 where he says, " This bed is no less than 90 feet wide, and large 

 masses project above the soil. It is situated near the mouth of the 

 first Seboois Lake, upon township No. T, Tth range," etc. 



Last year we prepared a Geological Map of Maine upon an un- 

 colored copy of Chace's map, thus exhibiting at a glance all that 

 was known respecting the geology of the whole State, and pre- 

 sented it, with the Report, to the Legislature. We shall do the 

 same thing this year, and shall be able to color many spaces that 

 were left blank before. It will be upon exhibition in some portion 

 of the State House, while the Legislature are in session. 



We shall also exhibit at the State House an enlarged colored 

 copy of the section we' measured through the widest portion of the 

 State, viz., between Eden and the Canada Line. It will be sus- 

 pended very near a set of the specimens which were collected 

 along the route. It is designed both to show the character of the 

 rocks as they appear at the surface along a given line, and to rep- 

 resent the supposed relation to one another which the respective 

 formations have beneath the soil. 



It is possible that persons in different parts of the State have 

 been expecting to see us in their towns during one of the past two 

 seasons, and not having seen us, may have thought we have not 

 appreciated the importance of their rocks. We can only say, if 

 such be the fact, that we have been as expeditious as possible in 

 our field-work, and that our apparent neglect has arisen from the 

 impossibility of being in two places at the same time. If any per- 

 sons are very anxious to have the rocks of their neighborhood ex- 

 amined in the future, we would suggest to them the desirable- 

 ness of informing us of their wishes, so that our plans of action 

 may be made to coincide with their wishes.
