The above facts place great responsibility on the city governments 

 which onuiit to b(^ recognized. Tt has bc(Mi said that the Illinois law 

 against Canada Ihistle would absolutely control tiiat pest were it not 

 for reinfestation by seeds blown and transported from the city of 

 Chicago and other large t(nvns in that state. The pul)lic welfare 

 demands that every city awaken to its responsibility and start an 

 annual cleanup campaign. The agricultural interests of the state 

 should demand that a general policy of cleanness be inaugurated and 

 carried out. 



This can lie and has been accomplished l)y many cities by turning 

 its vacant lots over to the public, as parks and playgrounds, as free 

 agricultural plots, as places for school gardens and the like. Where 

 large areas are going to waste the city park commission should pasture

sheep and goats. This has been tried in many large eastern parks 

 and found of great value economically. JNIuuicipal legislation should 

 establish park and street superintendents, and it should be their duty 

 to keep the streets and lots clean to the best of their ability. 



WALKS AND STREETS. 



It is an easy matter to keep walks and streets free from weeds. 

 Here the soil is of no value and chemicals can be applied which will 

 sterilize and thus prevent all growth. In the city of Sacramento 

 street cleaners spend hours digging and hacking at Bermuda grass 

 patches which could be ivmoved in five minutes by the apitlication 

 of a little di.stillate. Such chemicals as distillate, eopper sulphate 

 6 per cent solution, salt or any strong soil-killing chemical will remove 

 all weed growths from walks and drives for a period of several months. 

 Material should be sprinkled on with an ordinary sprinkling pot to 

 get the best results.
