vorable to vegetation, such as several salta of ammonia, phosphate of 

 lime or the chief component part of bonedust in abundance, potash, 

 soda, and as much as one third of organic matter, which would fur- 

 nish humus with a little clay and sand. 



Immediately on receiving this guano, about the 17th June of this 

 year, I commenced my experiments, which I will now explain in or- 

 der, and as briefly as possible. 



First observing that all those plants which were treated with guano 

 were potted in a mixture, consisting of plain earth without any ma- 

 nure, sand, and a little leaf mould and peat, with which the guano 

 was mixed — that those plants which compare with them have been 

 grown in our richest compost — and that both have had the same at- 

 tention, and been grown otherwise under the same circumstances. 



Fuchsia fulgens — one year seedline, potted 17th June, two and a 

 half inches high, with one teaspoonful not piled up, of guano — repot- 

 ted 9th Aug-ust, then twelve inches high, with another spoonful of 

 guano — is now one and a half foot high. 



The contrast between this and the two years' old plant is very 

 striking, both as to luxuriance of growth and color of the foliage, the 

 plant with guano being vastly superior. I think also that the color 

 of the flower is improved; it is well known among gardeners that it 

 is rather difficult to grow this plant well. 



Pelargonium — two seedlings grown with guano, and one of the 

 same sowing without: on the 17th June these two were potted with 

 one teas])oonful of guano, and repotted on the 9th August with an- 

 other teaspoonful; here also the difference in favor of guano is very 

 great. 



China Roses — two cuttings with guano, potted 17th June, with one 

 teaspoonful guano — one was then seven inches high, the other four 

 and a half; they are now thirty-four inches and twenty-eight inches 

 respectively, with large healthy foliage and stem; these have not re- 

 ceived a second application of guano. 



Celdsia cristaia or Cockscomb — one seedling, with one teaspoon- 

 ful and one of the same sowing without — the size of the stem, foli- 

 age, and head of that with guano is more than double that of the oth- 

 er, and the diflference in the green color of tho leaves remarkable. 



Salvia patens with one teaspoonful of guano — the effect here has 

 been to lengthen the joints, and the flower appears a trifle smaller 

 than usual. 



Jlckc'm FarnesittTia — a seedling showing the size of the foliage and 

 length of the joints, previous to the application of a teaspoonful of 

 guano, and the remarkable growth of both afterwards. 



Camellia with two teaspoonsful, I7th June, and none since. This 

 specimen which was quite small and unhealthy before the addition of 

 guano, as may be seen by the lower leaves, exhibits in a most mark- 

 ed manner, by its beautiful large deep green leaves and healthy bud, 

 the action of this manure. 



I have also exhibited a Camellia grown with a large proportion of 

 fine wood charcoal; the foliage and bud is extretnely fine and luxu- 

 riant, and of a very healthy green color, but, as may be seen, not at 

 all equal to that worked with guano. 



One Balsam, 17th June, two teaspoonsful, repotted 9th August 

 with two more, to which a little lime was added.
