ceptions to the last, I am sure that all butter for export should 

 be made from pasteurized cream. 



Then, and then only, can we hope to work up a reputa- 

 tion for clean, pure flavor, combined with uniformity, which 

 is all important on the world's market. 



It is not my province here to treat buttermaking, but 

 must emphasize the futility of pasteurizing the cream, if the 

 butter afterwards is washed with any kind of water, a custom 

 which 1 regret to say obtains generally. 



If the water supply comes from a deep drive well it may 

 be safely used, but in all cases it would be money well spent 

 for any creamery to have it analyzed chemically and bacter- 

 iologically. 



Where the water comes from shallow, open wells, or is 

 pumped from creeks or rivers, it should always be boiled or 

 filtered, at least all that is used for rinsing the cream vat, the 

 churn and the butter worker, as w r ell as for washing the but- 

 ter. 



PASTEUR FILTER. 



This filter which I regret to say requires a pressure of 

 at least 20 fibs, to the square inch to do practical work, and 

 which is rather expensive, is not only a filter, but a complete 

 sterilizing apparatus, as no microbe, no germs of microbes 

 even, can pass through those wonderful hollow "candles" 

 made of a composition of unglazed porcelain, prepared by Pas- 

 teur's associate, Prof. Chamberlain. 



The idea of sterilizing milk this way lay near and would 

 obviate the dreaded boiled flavor, but alas and alack, this 

 filter is so powerful that only a very clear "whey" would be 

 the result. 



I have had some correspondence with the company in 

 Dayton, Ohio, and they tell me that a filter for 250 gallons a* 

 day, which, I presume, would be enough for the average 

 creamery, if used only for the washing of the butter would 

 cost somewhere about $100, and this should not prevent their 

 use if they prove otherwise practical. I refer to the trouble 

 of cleaning the "candles" every day. 



I hope to see this filter given a fair trial. 



If our experiment stations had taken this matter up in a 

 practical manner, I am sure they would long ago have demon-
