OBJECTS OF THE PEACTICAL EXPERIMENTER, 85 



1. How far the natural soil of his farm may be improved 

 by this or that process, or by this or that application. 



2. How his crops may be increased in quantity, improved 

 in quality, or protected from this or that insect, or from this or 

 that form of blight. 



3. How this or that kind of waste upon his farm may be pre- 

 vented, and the natural fertility of his land be thus economised. 



4. How this or that refuse substance of the farm or the 

 manufactory may be applied to an economical use. 



5. How the manures at his command may be made to go 

 farthest, or produce the greatest economical effect. 



6. What single or mixed manure ought to be given to a 

 particular crop on his particular soil. 



7. What special additions the manure made on his farm 

 requires, to fit it for this or that particular crop, owing to the 

 way it is prepared, to the kind of husbandry practised, the kind 

 of produce sold off, and so on. 



8. When and in what state the different manures he has at 

 his command may be applied most economically on his soil, in 

 his climate, and for the crops he especially wishes to grow. 



9. Ought the manure to be given to the land all at once, or 

 at two or more several times during the season or the rotation ? 



10. If not all at once, ought all the ingredients of a mixed 

 manure to be given together in a state of mixture part of 

 the mixture atone time and part at another? or ought some of 

 the ingredients to be applied singly at one season (the spring 

 or autumn) or at one period of the rotation and some at another, 

 on his soil and for his crop ? 



11. Ought some, for example, to be given when the plant 

 is young, others when it has grown to a certain height, and 

 others again when it approaches maturity -*- to produce the 

 greatest apparent effect or actual profit ? 



12. How the produce of his farm may be most economi- 

 cally made use of, in rearing, feeding, and fattening cattle, or 

 in producing milk, butter, and cheese how the quality of these 

 dairy products may be improved how they are best preserved, 

 and so on. 



Such inquiries as these the practical man makes ; and, by
