gravel and rocks and having movcd the surface soil from 

 place to place. In this connection the lecturer mentioned 

 the gravel ridges extending from Andover to Beverly as 

 being caused by the settlement of the moraines of the gla- 

 cier, also many hills in Boxford and other places and 

 other deposits of boulders, etc. The course of the Merri- 

 mac river was also claimed to have been changed from its 

 original direction by the deposit of similar moraines or 

 rido:es of Sfravel and sand besfinninsf at Lawrence. 



Mr. Perley suggested that the members of the Essex 

 Institute interest themselves to a greater extent in the 

 study of geology, and that they cause to have made a sur- 

 face survey of this section of the country. 



Monday, Feh, 27, 1893,— Mi\ Alfred Stone, of Prov- 

 idence, lectured in Academy Hall on "The Great White 

 City ; or an Architect's View of the World's Exposition 

 Grounds and Buildings." His remarks were illustrated 

 by a series of stereopticon views taken from the buildings 

 uow completed and also under process of construction. 

 Mr. Stone first showed a plan of Jackson Park as it was, a 

 desolate swamp, and then a map of the grounds and loca- 

 tions as they have been arranged for the exposition. 



He then proceeded to describe and show by his views 

 the principal buildings. The Administration building he 

 termed one of the finest examples of architectural art. The 

 Manufacturers and Liberal Arts building he described 

 fully ; said that Bunker Hill monument set down in the 

 main aisle, would not reach to the top of this building ; at 

 the time of the dedication exercises, 90,000 were seated 

 in this building. The other buildings were shown and 

 described. He spoke enthusiastically of the proposed ex- 

 hibit by the Institute at the fair, to be in the Massachu- 

 setts building, regretting that he was unable to show a 

 picture of that building.
