Excerpt from Report on a Re-Examination: Of the Economical Geology of Massachusetts

Sir, - The commission with which I was honored, to make a further Geological and Mineralogical survey of the State, was not received in season to enable me to enter upon the work till towards the conclusion of the last summer. From that time to the present, I have devoted myself to it almost without cessation.

I was directed to give special attention to five leading objects. The first was the collection and analysis of our soils, with a view to their improvement on chemical principles. The second was the discovery of coal, marl, and ores. The third was a re-examination of some of the rock formations, so as to determine more accurately their limits, that they may be colored on the new Geographical Map of the State. The fourth was to make further investigations into our scientific geology, both with a view to advance the science, and to make a practical application of any new discoveries that might be made. The fifth was the procuring of new specimens of our rocks and minerals for the State collection.

It was obvious at once, that it would be impossible to accomplish all these objects in one season. Indeed, in regard to the third object, which in the commencement of the geological survey was regarded as the main one, want of time was not the greatest obstacle. For it never can be effected until the geologist can obtain at least an outline map, far more accurate than any that now exists, except of one or two counties in the vicinity of Boston.
