desirable that he vaccinate tnem because there you have public health problems that so far has not been satisfcatorily answered and until it is you cannot afford to make all of your milk producing cows reactors. If it is a pure bred dairy operation you have two reasons not to vaccinate your adult cattle. Now I am not arguing from the standpoint, or I am not discussing this from a standpoint of the effectiveness of the vaccine. All disease control in

livestock is a compromise, t^e have certain methods that we know will work,' We have industry that we are not desirous of wrecking. We apply knowledge to the. industry in the hope we will clean up the infection at the same time keep the industry just as prosperous as we possibly can. Therefore, our compromise is not with oir profit, it is with knowledge of disease control. Surely you could make a pure bred Guernsey as resistant by vaccinating as an adult as you can a grade Hereford calf but to vaccinate the grade Hereford calf or the grade Hereford cow does not seriously complicate the problem of profitably producing for that owner as it does for the pure bred Guernsey breeder. There is the problem that is always before us in regulatory work. If we are going to tell you to do something that we know will control the disease but at the same time will put you out of business you are just as well off not doing anything; better. I think that has contributed more to the confusion in the minds of the people on “who knows what to do about Bangls disease’* and “I don't think anybody does,” than anything else, because you seldom get four people arguing who are all in the same kind of cattle production and therefore the problem is different and the solution is different.

Soils are \'ery much like cows; some are good for one crop, some are good for another. No soil is good is good for much if it isn’t well taken care of.
