48 On Smut in fVheat, 



Having conducted this essay, solely with that view, 

 and directed the scattered rays of light on the principal 

 objects of inquiry, the prosecution of the subject, it is 

 presumed, will now, be rendered more easy to experi- 

 mental agriculturists. But since microscopical insects 

 and parasitical germs, in their infant state, are invisible 

 to the naked eye, and the diseases, apparently produced 

 by them, seldom discovered till the mischief be done, 

 farmers ought to be extremely vigilant, in the timely 

 application of the most rational means of prevention : 

 Whether they adopt the present plan, or any other 

 course of experiments, they are requested to favour the 

 Society annually, with the result of their observations. 



If the preceding pages should put them on their guard 

 against drawing hasty conclusions, from fallacious ap- 

 pearances, and facilitate the experimental inquiry pro- 

 posed, on a subject so interesting to the country, the 

 author will think his labour has been well bestowed.
