QUESTIONS AND ANSWERS. 235 



ing animals should be fed after a feed of hay. If a peck cf 

 meal, for instance, is fed in the morning before hay is fed, 

 a large portion of that goes off undigested. I suppose ' that 

 one of the advantages derived from steaming feed is the 

 fact that the meal is so thoroughly mixed with the hay, or 

 with tlie cut ,feed : hence, if the meal, or shorts, or whatever 

 the grain maj'" consist of, is thoroughly mixed with the food, 

 there is an advantage. That is my theory. 



Question. Would you feed it dry, or moist ? 



Mr. Smith. It is better to feed it moist to milch cows. 

 It makes more milk. I do not know that it makes more 

 tallow. 



Mr. Flint. The next question is, Is it advisable under 

 any and all circumstances to avoid the use of green nitro- 

 genous manures in fertilizing grape-vines ? Dr. Fisher will 

 answer. 



Dr. Fisher. Wherever your soil is very poor, you must 

 feed them enough to grow your crops. In what I have said 

 about the use of nitrogenous manures for grape-vines, I have 

 presupposed that they were on good fair land ; but the nitro- 

 genous element should not predominate. The poorer your 

 soil, the more nitrogen you may put into the field. 



Mr. Flint. Here is another question that Dr. Fisher can 

 answer very readily now that he is up, — 



Is there any wash that can be applied to the grape-vine 

 to destroy the steel-bettle, also the worm that injures the 

 clusters of grapes ? 



Dr. Fisher. No, sir. 



Mr. Flint. What is the cause of mildew on apples ? and 

 is there a preventive ? I will ask Mr. Had wen of Worcester 

 to answer that question. 



Mr. Hadwen. I do not know that I can answer the 

 question fully. We know that mildew exists on apples, and 

 we know that it exists on some varieties of aj)ples more than 

 on others. I suppose it is a fungus, and that it is stimulated 

 by certain atmospheric influences. I know of no remedy, 

 unless it be the universal remedy for fungi, which is sulphur. 

 It can be easily washed off with warm water. It is a curious 

 fact that mildew on apples and pears prevails more gener- 

 ally near evergreen trees. 



Mr. Flint. The next question is. Can the basket-willow
