192 ANNUAL, REPORT OF THE Off. Doc. 



DR. TOWER: I am not much of an advocate of molasses as 

 feed. 



A Member: How about ground linseed oil cake? 



DR. TOWER: I am not much in favor of it. 



MR. BEARDSLEE : Doctor, can you describe the process of milk 

 secretion and its delivery into the udder? 



DR. TOWER: I haven't the time to do that. 



MR. BRODHEAD: Doctor, in reference to a horse not having 

 their teeth in proper shape, is not that the cause of colic in a horse? 



DR. TOWER: In about eight cases out of ten, I would say that 

 colic comes from bad teeth. 



Now I will not detain you long but I have a little more to present 

 to you in the paper that I have prepared. Referring again to the 

 cow, let me say again that she is the most complicated piece of 

 machinery that was ever built. If this be true, then the man who 

 takes upon himself the care and management of this animal, must 

 be a machinist of the highest order. He must be able to select, 

 or in other words, build up a machine that is capable of earning 

 more than it consumes. He must know v;hat kind of feed or fuel, 

 if you please, to use in order to get the power. The man who runs 

 the steam-engine has only the one machine in his charge, and when 

 once he is become acquainted with i(s workings, he has mastered 

 the situation. If a certain part of the machinery breaks or be- 

 comes worn by use, duplicate parts can at once be obtained. Not 

 so with the dairyman; he may have forty or fifty of these com- 

 plicated animals in his charge, and no two require the same treat- 

 ment or care. The farmer may study the needs of one cow and be 

 able to say for a certainty just what she requires to keep her in 

 perfect condition and at the same time pay the most profit, but 

 when he comes to cow No. 2, he finds another problem and so on 

 through the herd. 



If we were to go to the National Museum and -see the first locomo- 

 tive that was built and compare it v>ith those of to-day, we would 

 scarcely think they were made for the same purpose. Exactly so 

 with the cow; lier outward appearance does not present such a 

 marked contrast, but her earning capacity has been greatly in- 

 creased. We can remember when a cow that could make one pound 

 of butter in a day was considered a wonder. Now if a cow will 

 not make four or five pounds in a day, she is no good. 



Years ago anything that had a head and horns on one end, a leg 

 on each corner and a tail on the other end, was a cow, one just as 

 valuable as another. Nobody knew what amount of butter fat 

 her milk contained. Nobody knew or cared what a balanced ration 

 was. 



What has caused the change? It has not come by chance, it has 

 come by close, hard study, by experience, by using the different kinds 

 of food to see which would produce the most milk. A few years 

 ago, if a cow sold for |100 it was considered an exorbitant price. 

 Not long ago H. D. Roe, of New Jersey sold Aggie Cornucopia 

 Pauline for |5,500. You may say this is simply a fad; if so, then
