story, but there is some indication of the real facts, especially 

 for the last three months of the year when we began making 

 regular daily tests, Sunday excepted, This is done for the 

 sake of the school and the homes furnishing students, or 

 offering board or lodging for them. It has been done freely, 

 with the hope of serving the community as well as the school. 



In the light of the fact that we are to have treated water 

 soon, it will be more important to have data for comparison 

 later. One thing that does not show is, that after fires in the 

 city the water was much more likely to have B. coli present in 

 it, or at least showing in the hydrant. Again, this has been an 

 exceptionally wet year. The Neosho river — the source of our 

 supply had floods or high water in it an unusually large pro- 

 portion of the time. This accounts for the amount of gas 

 showing in it. We have had but little typhoid fever. In my 

 opinion it has been because of the freedom from this disease 

 on the watershed, rather than because of the treatment which 

 the water receives.

1. SOME PECULIAR LICHENS COLLECTED AT OSWEGO, KAN., 

 SEPTEMBER, 1915. 



WHILE collecting plants near Oswego, Kan., on the 4th of 

 September, 1915, we collected what seemed to us to be 

 hybrid lichens. At least there seemed to be two distinct spe- 

 cies, with intermediate forms grading into each other. 



The one I judge to be Cladonia Pyxidata (L.) Fr., the brown- 

 fruited lichen ; and the other Cladonia rangiferina (L.) Hoffm., 

 one of the "reindeer lichens." 



The intermediate forms pass from the former to the latter 

 by a gradual disappearance of the scales and lobes character- 

 istic of C. pi/.ridata, and a gradual assumption of the upright, 

 much-branched habit of the reindeer lichens. 



Lichens are symbionts, consisting of various fungi associ- 

 ated with various algae, and as these were growing more or 

 less intimately, it is reasonable to suppose that the various ele- 

 ments of the two s>Tnbionts might be somewhat forced into an
