306 ANNUAL REPORT OF THE Off. Doc. 



years to test out the efficiency of these wind bufflers. Tliere is a 

 little more glass put in the house to make up for the darker effect 

 of the wind bufller in place of muslin. This picture (Fig. 23) gives 

 a little better idea of the wind bufifler, cut right down through to 

 show the arrangement of baffle plates. You can see what the prin 

 ciple is; the wind, blowing from the front of the house, comes up 

 and strikes that louver there and whirls, it comes up in here and 

 whirls around over here and makes a counter-whirl so that it can- 

 not get into this house until it has turned over several times and 

 then reversed itself in the other direction. A person can stand two 

 feet behind this wind buffler in the house with a heavy head of 

 wind coming from the south and never know that the wind is blow- 

 ing. The snow cannot get in, the rain cannot get in, but the air 

 can change place through all the half inch or three quarters. 

 The air circulates more freely than where muslin curtains are 

 used; and that enables a person to put these wind baffles in the 

 front of his house without ever having to touch them from fall to 

 winter, and j^our hens are never in a draft and always have per- 

 fectly clean, fresh air if the proper proportion of the front of the 

 house has the wind baffler construction. I know very well that I 

 have long since exhausted your patience. I ought not to have 

 brought so many lantern slides with me nor talked so long to each 

 slide. I apologize, and thank you very sincerely for your attention. 



FORTY POPULAR VARIETIES OF POULTRY 



W. THEO. WITTMAN, Allentown, Pa. 



Mr. Chairman, Ladies and Gentlemen: I am not at all disap- 

 pointed nor do I feel at all bad that Prof. Rice has taken so much 

 time. We poultry people at least give credit to Prof. Rice's stand- 

 ing head and shoulders above everybody else in this country in his 

 knowledge of poultry, and I am particularly pleased that he has 

 had the chance to give us all or at least part of what he knows 

 here this morning. I am especially pleased that he has given us 

 agricultural workers of this State a message to take back home 

 that the farmers of the State of Pennsylvania should quit having 

 so many late hatched chickens. You know quite a number of farm- 

 ers in Pennsylvania are just beginning to think of setting hens 

 or just beginning to have their first chickens, and here it is nearly 

 June 1. I am very glad that he has shown us here on this screen 

 that 60 eggs is a very low egg yield, and I am sorry that the 

 farmers of the State of Pennsylvania showed in the census enumera- 

 tion of 1910 that their hens laid only 68 eggs. Take that message 

 back home so that in 1920 the farmers can give a better report 

 to the census enumerators. I am especially pleased that he brought 

 the message. We want pure bred chickens, and it is a shame that 

 in Pennsylvania some of our fine farms are disfigured and brought
