though the Swedish population is quite large. There 

 are also many negroes, mostly in the southwest part of 

 town, some Irish and Germans, a few Italians, fewer 

 Slavs, and a small colony of Mexicans, most of whom are 

 employed by the railroads. 



Water Supply. Galesburg is well supplied from the 

 St. Peters and Potsdam sandstones. There are three 

 wells in use ranging from 1,245 to 2,240 feet in depth. 

 The city pumping plant contains seven pumps, five of 

 which are emergency pumps. There is in connection with 

 the pumping station a reservoir of about 6,500,000 gal- 

 lons capacity with a daily consumption at the present 

 time of about 1,250,000 gallons. The reservoir itself is 

 in need of more adequate protection against pollution, 

 and better fencing should be used to keep trespassers 

 off the premises. During the summer months, the water 

 receives copper sulphate treatment for algal growths 

 and is tested each week by the state bacteriological offi- 

 cers. 



Milk Supply. The milk supply is not so adequately 

 protected. In the first place there is no adequate super- 

 vision by the city authorities of either dairy herds or 

 dairies. The state inspection of dairy cattle is not 

 checked up by the city health authorities and in conse- 

 quence some milk from tubercular cattle sifts into the 

 city milk supply. Some of the dairies are sanitary and 

 would comply with a moderate grade of inspection, but 

 several of them are notoriously dirty. Pasteurization 

 is made by some dairymen, while others supply raw milk. 

 Tests made at the laboratory of Knox College of several 

 different milk supplies revealed usually a high butter 

 content but also a high bacterial count. There is need 

 of this city adopting the standard Pasteurization re- 

 quirement now being adopted by many cities of the state, 

 but this requirement would be inadequate with the pres- 

 ent health machinery of the city. 



Protection of Health. At the present time the city of 

 Galesburg has no adequate health department capable 

 of maintaining health standards. There are on the stat- 

 ute books many model sanitarj^ statutes although no sani- 

 tary code as such has been compiled. There is, however,
