116 BOARD OF AGRICULTUEE. [Pub. Doc. 



Question. Let me ask you how many barrels ran oflf in 

 a day that way. 



Professor Brooks. It is difficult to estimate, but that also 

 I calculated. Let us suppose it was an exceedingly heavy 

 rain, two inches, and if I am right in my recollection as 

 to the value of this material in a rainfall of two inches, 

 was under two dollars per acre. Now, understand me. 

 I do not advocate the spreading of manure on slopes 

 covered with ice. Put it in the winter as far as practicable 

 on level land, upon grass where there is no slope, and where 

 there will be no wash, and I have no evidence of any instance 

 where there is any loss. I have always noticed, where the 

 manure was put on in the late fall or early winter, the crop 

 was much better than where it is put on in the spring. 



Question. How much loss is there in manure such as 

 usually comes from Boston ? 



Professor Brooks. There is undoubtedly considerable 

 loss. This Boston manure has in many instances lost a good 

 part of the urine, which is often let right into the sewer and 

 carried off, the only object being to get rid of it. 



Question. I would like to ask the professor whether he 

 calls manure made from the stock in summer green manure, 

 or not ? 



Professor Brooks. No, sir ; I should simply call it fresh 

 cow manure or barn-yard manure. 



Question. Would you apply that in the winter, and 

 not plough it in ? 



Professor Brooks. Yes, I would use it for any ordinary 

 purpose of the farm. We generally put it on as soon after 

 it is made as we can. I advocate putting it on while it is 

 fresh. 



Question. We are making green manure during the 

 months of July, August and September. What would you 

 do with it ? Would you put it on top of the ground ? 



Professor Brooks. If the condition of the helds on the 

 farm permit, I should put it on about as fast as it is made. 

 If I did not have any fields in condition to put the manure 

 on, I should be forced to let it accumulate on a water-tight 

 surface, with a roof overhead. I should want to scatter 

 on it occasionally an absorbent, such as plaster or kainit,
