12 THE NAUTILUS. 



was the first place I had any opportunity to see them in any num- 

 ber in the north of Maine. From this place I had intended to go 

 to Big Fish Lake, about 20 miles west from Portage Lake, but some 

 of my provisions were spoiled by hot and rainy weather and I was 

 not able to obtain any from the farmers, therefore at the south of 

 the lake I engaged a team to transport us to Aroostook River, a 

 distance of 10 miles, over a good road. 



Aroostook River is rapid and rocky the whole distance from Ash- 

 laud to Caribou, and shells are seldom found. Margaritana mar- 

 garitifera Lin., are found among the rocks in from 5 to 6 feet of 

 water ; a dozen living specimens were obtained in the distance of 40 

 miles. Anodonta fragilis lives in the small streams which empty 

 into the river. Planorbis bicarinatus and Physa heterostropha are 

 sometimes plentiful. Sphcerium truncatum and a few Pisidia have 

 been found. Campeloma decisum were collected in two places, and 

 Ancylus tardus Say, was found on rocks in a place near Caribou in 

 the summer of 1895. 



After three weeks have been spent in the woods it is pleasant to 

 arrive at home again. The specimens collected during this trip 

 have not all been identified. 



In past years I have received valuable assistance from Professor 

 H. A. Pilsbry. Mr. Bryant Walker, of Mich., sent me a dredge 

 which has been of great value, and Dr. V. Sterki has kindly deter- 

 mined Pupidce, Vertigos and Pisidia. My thanks are due to these 

 gentlemen. 



TO SUBSCRIBERS. 



We wish to impress upon our readers that subscriptions to THE 

 NAUTILUS are payable in advance, and that we do not discontinue 

 until notified. Were it not that some subscribers forget to pay at the 

 end of the year it would not be necessary to thus emphasize the terms 

 of subscription. What is a small matter to each individual reader, 

 becomes in the aggregate a large one to us. Our deficit in publish- 

 ing Vol. X has been somewhat less than in the previous year, but 

 is still more than we can afford to lose. Our screed upon this topic 

 in January seems to have been misunderstood by some cautious per- 

 sons we have heard from, who for fear THE NAUTILUS would be dis- 

 continued, kept their dollars ! With this kind of support we could 

 not have continued another month ; but stalwart friends of the cause 

 in Massachusetts, Michigan and California said " THE NAUTILUS 

 shall not stop ; we will stand by if needed." With this assurance 

 we enter upon another volume. 



All who are in arrears are requested to " pay up " this month. 



H. A. P. & C. W. J.
