rendered much more luxuriant than 

 others having no guano. Brussels Sprouts 

 were half destroyed by being planted in 

 immediate contact with nine parts earth 

 and one part guano. Geraniums were 

 greatly injured by liquid-manure of guano 

 U'our ounces per gallon), but "plants of 

 various sorts, in pots, watered only with 

 guano-water, half an ounce to a gallon, 

 have flourished astonishingly ; none have 

 failed. These are lessons which cannot 

 be mistaken." Auctorium, 223. Mr. 

 Hendle and other persons record, as the 

 result of dearly-purchased experience, 

 that where guano has failed to be bene- 

 ficial, or has been injurious, it has been 

 applied in quantities too powerful for the 

 plants to bear. In a liquid state, half an 

 ounce per gallon, and given to growing 

 plants once a week, it never fails to be 

 productive of vigour. When sown as a 

 top-dressing, it should be mixed with five 

 times its weight of dry earth, ashes, <fec., 

 and then scattered as thinly as possible. 

 When used as atop-dressing for a flower- 

 pot, a small pinch between the thumb 

 and two fingers will be sufficient. 



Cow-dung, for potting purposes, should 

 be collected whilst fresh, kept under a 

 dry shed, be frequently turned over, and 

 used when in a dry, loose condition. 

 Two years' old dung is best.
