formation should be given. Annexed to tbis sketcb will be a notice 

 of the rocks of Vinalhaven, by George L. Goodale. Then will follow 

 a detailed account of the measurement of a geological section by us 

 the past summer between Mount Desert and the Canada line, by the 

 way of Bangor and the Forks of the Kennebec river. This is 

 really one of the most valuable results of our summer's work. 



Under this head Dr. Holmes will give some account of the 

 geology of Oxford, Franklin and Kennebec counties ; being the 

 results of many years observation. Possibly we may add a few 

 words to it. 



B. Reports upon the geology of the Schoodic waters, near the 

 eastern boundary. These include the eastern Schoodic lakes, the 

 western Schoodic lakes, and a portion of the St. Croix river, and 

 consequently pertain chiefly to an unsettled region. Perhaps we 

 may make a few remarks upon the geology of a portion of New 

 Brunswick in this connection. 



G. Reports upon the more northern and unsettled portions of 

 the State. These are upon the region of the great lakes in north- 

 ern Oxford and Franklin counties ; upon the vicinity of Moosehead 

 lake ; upon the country watered by the upper portions of the west 

 branch of the Penobscot and St John rivers ; upon the Alleguash 

 lakes ; upon some portions of northern Aroostook county, particu- 

 larly the results of Dr. Ilolmes' explorations among the Lower 

 Helderberg limestones in search of the marble layer. 



D. Surface geology in general ; or a summary of our observa- 

 tions upon the geology of the Alluvial Period, in addition to what 

 was said respecting it last year. We shall be able also to pre- 

 sent something respecting the microscopic animals and plants of 

 the infusorial deposits found sparingly beneath some of our ponds. 



E. Descriptions of new species of Devonian and Silurian fos- 

 sil plants and animals, by Dr. Dawson and Mr. Billings. 



F. Mincralogical Notes. 



G. Economical Geology. 



After having travelled over the State the second time, we were 

 surprised and gratilicd to learn how few errors of statement and 

 generalization are to be found in our preliminary report. Where 

 one is obliged .to infer from the observation- of others so much as 

 was done in that, there is great danger of misstatement. Wher- 

 ever errors of any consequence occur, we feel bound to correct 

 them ; for we are striving to attain a knowledge of the true distri-
