good earth — care being taken that they should be intimately blend- 

 ed and sown broadcast, in the proportion of about three hundrec 

 weight of the guano to the acre. Another method is to drop il 

 in the drills ; but, if guano alone is used, care should be taken tha* 

 it does not come in contact with the plant, as it will kill the plan 

 almost as surely as fire. 



It should also be applied, if possible, just before the coming 

 of rain ; for if left dry upon the surface, the volatile salts wil 

 soon evaporate. Thus, in a dry season, guano has been known ti 

 fail entirely — producing no effects whatever. 



The natives of South America are obliged, from the dryness o 

 the atmosphere, to irrigate their fields by artificial means, i 

 very beneficial mode of using is, to make a solution of guano, an 

 let it stand in a vessel, ready for use ; this will do only for garde 

 and pot plants ; although it might be pursued, perhaps, advantage 

 ously, upon large fields. Extraordinary effects have been produce 

 in this way. One mentioned in third No. of Colman's " Europea 

 Agriculture, &c. :" 



" In Scotland, last autumn, two shrubs were shown to me, swee 

 briars, growing in front of a two story house, and trained upon i 

 sides ; one at one, the other at the other end. The soil in whi( 

 they grew, the aspect and other circumstances, were the same. 



" One, in the season, had grown six or seven feet; the oth«( 

 nearly thirty feet! It actually climbed to the roof of the hous; 

 and turned and hung down, reaching half the distance down fro 

 the roof to the ground. I judged this could not have been le 

 than thirty feet. This had been repeatedly watered with liqu 

 guano, by the hands of its fair cultivator ; for this was another e: 

 periment by a lady, (which I hope my American friends will bear 

 mind.) The other had received no special care or manuring." 



The minutiiE of many experiments might be given, to showth 

 the value of guano has not been over estimated, so far as regards ififc 

 use in Great Baitain. Experiments in this country have not pr 

 duced such striking results, although it has been used here with ' 

 good deal of benefit, especially on house plants. 



A friend of ours has used it upon his garden vegetables, with excf ' 

 lent results, this season ; beets, tomatoes, tScc, were watered with 

 solution of guanoj with very marked results. The proportions
