Although the greater number of the tubes found 

 in the brook were constructed of mud, and had a 

 smooth external surface, I have sometimes found 

 the exterior rough with coarse sand grains, or bri st- 

 ing with bits of straw and other refuse which had 

 washed into the brook. 



In a brook in the woods, in Canton, Mass., I 

 found cases composed entirely of sand. They 

 were quite small and contained no larvae. Fig. 6 

 is added to show a form of case sometimes seen, 

 having two openings at the top of the chimney 

 instead of one. 



General Meeting, October 4, 1882. 



The President, Mr. S. H. Scudder, in the chair. Thirty- seven 

 persons present. 



After the record of the previous meeting was read and ap- 

 proved, the President spoke in fitting words of the death, at the 

 beginning of the summer vacation, of Professor William Barton 

 Rogers, who was elected a Corresponding Member early in the 

 Society's history, and became a Resident Member in 1857, having 

 previously been elected an Honorary Member in 1842. It was 

 voted that the chair appoint a committee to secure a memorial of 

 Professor Rogers for the Proceedings. Messrs. F. W. Putnam, 

 23*. S. Shaler and T. T. Bouve were accordingly appointed. 



Mr. F. ~W. Putnam then gave an account of some shell-heap ex- 

 tions made during the summer in Muscongus and Damariscotta 

 Bays, showing part of the collections made, including bone fish- 

 hooks, spears, awls, etc., broken pottery, together with stone ham- 

 mers, celts and other implements.
