Guano, its origin, properties, and uses. 187 



actual products of crops are stated, where it has been apphed 

 at the rates of one, two, three, four, and five hundred weight 

 and upwards, per acre. 



We are glad to see the attention which is now directed to 

 this vahiable fertihzer. Several cargoes of the African have 

 been imported, and a fair opportunity will now be oflfered to 

 test its importance in comparison with other manures in our 

 climate. All that is wanted is correct information relative to 

 its use, that the first experiments may not be unsuccessful. 

 To this end the pamphlet is directed. 



For the information of those who may not see this work, 

 we extract the following, relative to the proper quantity per 

 acre, and the mode of application : — 



"1. If intended for drill-husbandry, or to be used in the hill, it should be 

 mixed in the proportion of one part Guano to four or five parts of woods- 

 earth or mould, or any other fertile earth, or thoroughly decomposed ma- 

 nure — or one part Guano, one part ashes, and three parts rich mould or 

 well-rotted manure. 



" 3, It is best for the above purposes, not to let the mixture come in im- 

 mediate contact with the seed. 



"3. For broad-cast application, it may be sown as plaster is, after it shall 

 have been reduced into powder, either by itself, or in compost, as prescribed 

 in Rule number one. Whether used alone or in compost, it should be sown 

 and harrowed in, after the crop may have been sown and ploughed in. 



"4. It may be sown in compost, after a crop may have come up. 



"5. It is a good and highly fertilizing manure for all descriptions of 

 crops, whether grain, grass, or roots, and if properly used, will not only 

 increase the quantity of the product, but improve the quality also. 



"6. For root crops, 200 lbs., used in compost, as named in Rule number 

 one, is sufficient for an acre of ground — and the same would be sufficient 

 for an acre of corn, if used in the drill, or hill. 



" 7. For wheat, rye, oats, barley, tobacco, or any of the grass crops, 

 from 200 to 300 lbs., according to the quality of the land, will be found 

 sufficient for an acre. 



" 8. It should, if possible, always be applied in wetwe&ther, and covered 

 lightly either with the plough or harrow : where neither of these modes 

 may be practicable, after sowing Guano, the roller should be applied. 



"9. In applying it to old meadows, or meadows which may have been 

 set for some time, it should be harrowed in and then rolled. 



" 10. If convenient, plaster may be very advantageously used with it, in 

 the proportion of one bushel of plaster to 100 lbs. of Guano. 



"11. In applying it to grass lands and meadows, the month of April 

 would be the most suitable period, £is a great object is to dissolve it, in order
