532 ANNUAL REPORT OF THE Off. Doc. 



MR. COOK: If you want to go to work and dig away there, yes, 

 I think that would be very much better; you did not suggest that 

 idea. Let me give you another way, if you want to sit just a 

 moment. It will often determine when you walk into a stable 

 whether the intakes and out-takes are well-balanced. Sometimes 

 when you open the door into a stable, you notice at once that the 

 air rushes out because you have pretty nearly compressed air in- 

 side. In that case it is easy to see that the out-take flues, if they are 

 in there, they are not doing their work, or the air would not rush 

 out when you open the door. On the other hand, I have been in 

 stables where you would have to go in two or three feet before you 

 would begfn to feel the change of temperature — say the change from 

 the outside was twenty degrees, you would not feel that until you 

 have got into the barn several feet, because there was not fresh air 

 enough coming in to provide the out-take flues with what they were 

 called on to carry out; I can tell the whole story the minute I step 

 into the stable. 



DEPUTY SECRETARY MARTIN: And you often see a little 

 steam coming out. 



MR. COOK: Yes, that is wrong, anyway. 



MR, NELSON: I am sure we wduld all like to have a word from 

 Mr. Martin. 



DEPUTY SECRETARY MARTIN: Mr. Chairman and Friends: 

 You have indeed enjoyed a very rare opportunity at this meeting of 

 the State Board, for there is no question or any one subject which is 

 of greater importance to the dairyman of Pennsylvania than the 

 question of the construction of the barns in which you keep your 

 animals. The question of the old fashioned Pennsylvania barn has 

 been mentioned several times during the last session. What vou 

 need in these old Pennsylvania barns, above everything else, is light 

 and ventilation. I would commend to your careful consideration 

 the lesson which you have received from Mr. Cook this evening. It 

 is simple; it is plain; it is in line with the natural laws governing 

 ventilation; it appeals to our common sense in every line to which 

 our minds have been called this evening, and as we are in the midway 

 of our farmers' institute season, I wish to call the special attention 

 of the men who are engaged in giving instruction in Pennsylvania, 

 to the lessons we have received along this line. This has been one 

 of your opportunities, to procure a knowledge of the most approved 

 method of barn ventilation, and I compliment you upon that im- 

 portant point. 



Time would not permit nor would it be discreet that we should go 

 over, to any extent, the valuable lessons that have been developed 

 during this meeting. I know they will accomplish good results in 

 Pennsylvania. The field here in Pennsylvania is a broad one and 

 an important one, and the gentlemen who have come to us from other 

 states have let us into lines of thought that will no doubt be a benefit 

 to us, and I want to join my voice with that of yours this evening 

 in expressing our gratitude and thanks to these men from other 

 states, equipped as those men have been with knowledge of a prac- 

 tical kind, who have brought to us such excellent instruction during 

 the sessions of this meeting.
