this present time that the Department is receiving com- 

 plaints daily with reference to the pollution of some 

 streams. 



I have given this question of pollution of the streams 

 much thought and the Department now has a plan of 

 filtering refuse from the various manufacturing estab- 

 lishments throughout the Commonwealth which it will 

 recommend and which it knows from practical demon- 

 strations will absolutely prevent refuse from getting into 

 the streams and which can be installed at a very moder- 

 ate cost to the manufacturer or mine owner. I have had 

 this filter system patented, paying for same out of my 

 own personal funds, and will turn the patent rights over 

 to the Commonwealth of Pennsylvania insofar as the 

 Commonwealth is concerned. This system of filtration 

 is the fruit of much thought and time given to it by one 

 of the wardens of the Department, Mr. Albert, and my- 

 self and we know that it will do the work. The Depart- 

 ment will be pleased and intends to furnish blue prints 

 of this system to every manufacturer in this State and 

 will insist upon it being installed as it has so much 

 confidence in its practicability that it does not hesitate 

 to recommend its installation. This system of filtration 

 will take care of and purify refuse from tanneries, dye 

 works, chemical mills, oil refineries, mines, nitro glycer- 

 ine works and creameries. The Department has on file 

 in its office scores of letters from manufacturers in this 

 State who are only waiting for the blue prints to go 

 ahead and install this system. The Department has found 

 that the manufacturers as a whole are willing to co- 

 operate with the Department in its work, which is very 

 gratifying and now since it has something which it can 

 stand back of it expects to accomplish much along this 

 line of work. It is the biggest and most serious ques- 

 tion the Department of Fisheries of Pennsylvania has 

 to contend with today and, with the hearty co-operation 

 of all those who are interested in the preservation of 

 fish life in our streams, the Department expects to restore 

 the streams to their former pure state so that there will 

 be good fishing for all.
