THE CULTURE OF THE GRAPE. 293 



with liquid manure was resorted to with good effect, 

 yet the difference was very much in favor of the border 

 with the carcasses. More trials with like results, might 

 be added ; however, if these have been properly stated, 

 — and I am certain that my object has been to obtain 

 facts, riot to establish theories,— and that these trials 

 have resulted as above expressed, then there can be no 

 necessity for further testimony of mine, as it all tends the 

 same way, and the mere repetition of the trials would be 

 useless. The question now is, whether the experiments 

 have been fairly made. \ think they have ; that climate

 some degree, the results of similar trials in other localities 

 is very probable.

 glass battles, filled with rainwater, under the stems of 

 grape vines, that had roots about one and a half inches

No. 1, had a grain of guano, in the powder, added ; 

 the effect of this was, that, in forty-eight hours, the root- 

 lets began to put out from the sides of the root, and to 

 consume the liquid. I then took a small teaspoonful of 

 fhe guano and mixed it with half a gill of water, and, as
