THE CULTUEE OF THE GRAPE. 295 



No. 5, was the extract of meadow muck, which had 

 been under cover several years ; one pound of the soil, 

 to which was added a very little potash, was steejDed in 

 water several days, and strained off into a bottle, and ap- 

 plied as the roots consumed the liquid. This afforded a 

 suitable food, and the spongioles continued to grow and 

 increase rapidly for three weeks, when they received a 

 check, and ceased growing, and were changing color; 

 the bottle was removed, and the roots placed carefully 

 into one filled with simple rainwater again ; this saved 

 them, and they again began growing. The liquid, which 

 had before proved too powerful, was now supplied them ; 

 as they consumed the water in the bottle, they grew as 

 rapidly as before the check, and formed a fine, strong- 

 rooted vine, which is now in the border. 



No. 6, was manured with the liquid drainings from the 

 hog-pen ; although very much diluted, the first application 

 destroyed the young roots. In renewing the trial, the 

 liquid which had caused this, was used as the same ma- 

 nure, still further diluted, and the efiect was" good ; the 

 bottle was filled with roots. 



No. 7, was manured with the extract of the leaves and 

 young shoots, trimmings of the grape vine ; these were 

 steeped a few days, and kept warm ; when applied to the 

 water in the bottles, it was quite acid. This destroyed 

 life very soon, the acid being too powerful. On repeating 

 the experiment, and after applying the same liquid, when 

 the acidity had passed away, the roots made with vigor 

 and rapidity; this formed a plant, now flourishing in 



f^ soil. 



No. 8, was another trial with guano, in a more diluted
