10. Specimen 33 cm. long from Portage River, as above, August 6, 

 1901. Some 20 to 30 c.c. dark mud-like material, consisting mostly 

 of plant fibers, fragments of stems, etc.; one young shoot (apparently 

 of grass) about 18 mm. long. 



11. Specimen 36 cm. long from Portage Eiver, as above, August 6, 

 1901. Small amount of material of the appearance of fine mud; under 

 the microscope seen to consist for the most part of finel}^ divided veg- 

 etable matter and some filamentous algce. 



12. Specimen 47 cm. long from Portage River, as above, August 6, 

 1901. xlbout 150 c.c. of material composed for the most part of veg- 

 etable matter — short pieces of stem, etc. ; some pulpy vegetable matter, 

 probably roots or bulbs of some aquatic plant; insect larvie, occa- 

 sional fragments. 



13. Specimen 30 cm. long from Portage River, as above, August 6, 

 1901. Six to 8 c.c. of very fine material resembling mud in appearance, 

 almost entirely composed of vegetable matter; vegetable libers and 

 some filamentous alga? recognized. 



11. Specimen 11 cm. long from Portage River, as above, August 6, 

 1901, Only 2 to 3 c.c. of line "mud'', consisting of plant fibers, 

 fragments of stems, etc. 



15. Specimen 36 cm. long from Portage River, as above, August 6, 

 1901. Ninety to 100 c.c. of rather coarse dark material, mostly plant

 1901, Small amount of dark mudd}" material, mostly plant fibers and 

 small pieces of other plant tissues; considerable filamentous alga?; 

 insect larvffi (dipterous?), occasional. 



19. Specimen 37 cm. long from Portage River, as above, August 

 6, 1901. Some 20 to 40 c.c. of fine, dark mud-like material consisting

 material in which vegetable cells could not be made out. 



20. Specimen 34.5 cm. long from Portage River, as above, August 

 6, 1901. Fine material consisting mostl}' of filamentous alga3 and 

 partlj' digested tissues of other plants.
