trap are also found along the margin. The crystalline rocks near the 
border manifest the effects of shearing, although now reconsolidated. 
The shearing is believed to be a result of the marginal faulting, after' 
the deposition of the Triassic beds, because fragments of the reconsoli- 
dated sheared rocks are not found among the pebbles of the marginal 
Triassic conglomerates. 
The eastern boundary of the Trias follows an alternating north and 
northeast course. This is particularly apparent north of Middletown. 
Hence two systems of faults are inferred; one having a northerly 
course, the other trending northeast. Two members of the latter sys- 
tem have been traced for many miles obliquely across the Triassic belt, 
as well as along the oblique portions of the border. In consequence of 
the combined movements of the two systems of faults, the forma- 
tion as now exposed broadens northward; and in the Manchester dis- 
trict it is believed that the under sandstones, ordinarily seen along the 
western side of the monoclinal belt, are brought up and repeated along 
the eastern border. 
20. Geographical work for state geological surveys. W. M. Davis, 
Cambridge, Mass. (Read by title.) The work of our state geologial sur- 
veys does not at present come into close touch with a large number of 
our people. On the other hand, the teaching of geography in our schools 
is in a lamentably impoverished condition, chiefly because the teachers 
have no accessible source of fresh information concerning the physical 
features of their home states. It is the object of this paper to suggest 
a remedy for both of these difficulties. 
It is believed that if every annual report of a state survey contained 
a chapter on some group of local physical features, prepared with espe- 
cial regard to consultation and quotation by teachers of the state, a 
new interest in the work of the surveys would be aroused and a new 
vigor would be infused into the teaching of geography. In order to 
carry out this proposition successfully the work should be in the hands 
of trained geographers, just as studies in paleontology and petrography 
are in the hands of trained paleontologists and petrographere, properly 
educated in these branches of the general science. Relatively simple 
features should be treated first ; their systematic relations to features 
of the same kind in other parts of the world should be clearly brought 
out by descriptions, illustrations and maps ; the dependence of popula- 
tion and occupation upon the natural features should be emphasized. 
The chapters should be brief enough to attract readers who are not ac- 
customed to research in libraries; hence the advisibility of attempting 
the account of only a small part of a state in one report. In this way, 
an appetite for more material of the same kind would be created, while 
the expense that would be required for this division of the survey work 
would be a small part of the annual appropriation. In order to gain a 
wide circulation for the geographical chapter of the survey report it 
might be reprinted in the report of the state superintendent of public 
instruction and this issued as a pamphlet for distribution to the public 
schools. It can hardly be doubted that if this plan were successfully 
carried out an effective co-operation between the surveys and the 
schools would result, and both would be benefitted and strengthened by 
it. 
:'l. Facetted pebbles on Cape Cod. W.M.Davis. Referring to sug- 
gestions received from his colleague, Mr. J. B. Woodworth, by whom an 
account of wind-blast carving has been prepared for the American 
Journal of Science (January, 1894), Prof. Davis briefly described the oc- 
currence of facetted pebbles in the gravels of Cape Cod. At Highland 
Light the pebbles now exposed in a gravel bed at the top of the bluff are 
m process of carving ; specimens can be had in plenty. Along the 
southern side of the Cape, where the sea has cut a low cliff in the gravel
