REPORT.
Bacteriologically the quarantine and jail wells continue to give unsatisfactory results ; the total number of
organisms as well as the fœcal germs in them are too high for well waters, the organisms being of many
varieties.
The Camp well water is of fair quality containing only one fœcal germ in 5 cc., but the presence of an
unduly high number of non-fœcal germs on this occasion is an objectionable feature about it.
Chemically the Camp well water is softer than the other two samples.

REPORT.
Bacteriologically the water from the wells shows a falling off in quality from that of last year, though
it is not so bad as it was twelve months ago, when both the well samples were declared unfit for drinking
purposes. Both the total and fœcal organisms are more numerous than at the last analysis but among the
latter there are none of the susceptible varieties.
Unlike former occasions the general. well water contains more organic matter this time than the kitchen
well water, and some of it seems to be of animal origin.
