228 ANNUAL. REPORT OP THE Off. Doc. 



MR. HUTCHISON: Mr. Chairman, I would like to ask Prof. Owens 

 if the gluten meal would not be a great deal higher in protein. 



PROF. OWENS: Yes, if you wanted protein, then the gluten 

 meal would be the material you would want to get; of course just 

 what you want is the thing that requires consideration in deter- 

 mining what to use. 



MR. PHILLIPS: Mr. Chairman, it seems to me that there is an- 

 other question that comes in here; the gluten meal is a heavy, con- 

 centrated food, and cannot be fed in large quantities with impunity. 

 I think it contains somewhere in the neighborhood of five per cent, 

 of protein, and is the most successful food where that is needed. 



I want to say this, that there are other food products not quite 

 so high in protein, and yet very desirable as feeds, and in addition 

 to what the Professor has said, as to the requirements of a certain 

 number of pounds of protein that an animal ought to have in twenty- 

 four hours, there is still another important question and a very im- 

 portant one too, and that is the question of health. 



PROF. OWENS: Yes, you must always include in your standard 

 the health of the animal, which would be more or less of an indi- 

 vidual factor. 



QUESTION: Is there positively nothing in the signs of the moon 

 for planting crops? 



PROF. OWENS: I think as long as you plant upon the earth, there 

 is nothing in the signs of the moon. 



MR. HUTCHISON: Hasn't the moon an effect upon the tides upon 

 the earth? 



PROF. OWENS: Yes, certainly it has. 



MR. HUTCHISON: Might it not have some effect upon the earth 

 as well as on the tides? 



PROF. OWENS: I don't know that any effect has been dis- 

 covered. 



MR. HUTCHISON: Might it not be possible? 



PROF. OWENS: I do not say it is absolutely impossible; there 

 is more in nature than our philosophy includes. 



MR. R. P. KESTER: What difference between commercial nitrate 

 of soda and saltpetre? 



PROF. OWENS: Nitrate of soda is sodium nitrate. Saltpetre 

 is obtained largely from India and sodium nitrate is obtained largely 

 from Chili. Potassium nitrate, if you could afford that, would fur- 

 nish the two elements at the same time, would give you the nitrate 

 and potash both, whereas the nitrate of soda only gives the one. 



DR. FUNK: Which is the cheapest to use? 



PROF. OWENS: I haven't figured that out. You could easily do 

 that; any one can do that and arrive at the absolute amount of
