. Bulletin. 1901-13. Agriculture; Agriculture. 66 FARM WATER SUPPLIES OF MINNESOTA. ? • Source of water supply.—(See fig. 71.) Cistern at side of house. Type: Dug, with galvanized iron casing; circular, with flat top. Capacity: Sixty barrels. Use: Drinking and general farm purposes. Method of lifting: Iron pump. Sanitary aspect: Good. Cistern appears to be well protected in every way; surface of galvanized tank tightly covered with boards; top projects some few feet above surface of ground and thus eliminates all danger of surface water entering. Lakes, rivers, ponds, and springs.—An interesting feature on this farm is a salt spring. It is very troublesome, as it flows into a small creek near the farm buildings and com- pletely ruins the water for all farm purposes. The flow is probably no more than several barrels an hour, but even this small quantity is sufficient to impart a bad taste to the creek water. This spring water is quite similar in taste and appearance to the water in the few wells in that vicinity. A sample was collected for the pur- pose of studying the ohar- acter of these disagreeable ground waters of the Red River Valley district. Sanitary condition of farm- house and outbuildings.— House good; stables fair; privy poor, open vault en- tirely unprotected. Milk.—Made into butter; sanitary care good. Water-borne diseases.—None recorded. Analyses.—See page 79. No. 4. This is a badly polluted supply. The roof is the source of pol- lution, and unless suffi- cient water for a thor- ough rinsing of the roof can be wasted at the be- ginning of each rain it will be impossible to improve the water sup- ply. Under such con- ditions the water for drinking should be boiled or otherwise disinfected. Location of farm.—Hallock, Minn. Date of visit.—September 16, 1908. Size.—Six hundred and forty acres. Kind of farming.—Grain. Topography.—Drainage from the farm buildings flows in the direction of the creek. Source of water supply.—(See fig.
