These experiments have been made with reference to knowing 

 the true and exact effect of the several fertilizers on this ground 

 by top-dressing, as it is not desirable to plough or cultivate, 

 except in grass ; (the lot containing fifteen acres being kept fer- 

 tile use of the society, and for the purpose of holding the 

 annual shows,) and the result shows quite plainly that several 

 of the fertilizers cannot be used upon these lands, as a top- 

 dressing, to any profit. The soil is clay loam, rather cold, 

 retaining moisture unusually late in the spring. The tables 

 show that ashes is the only profitable fertilizer to be used as a 

 top-dressing here. For the two years the increase of hay is 

 much the greatest, and the only lot on which the increase of 

 hay paid for the fertilizer the first year, and the increase of hay 

 did not pay for fertilizer on any other lot for the two years. 

 The lot where guano was used, gave greatest increase of hay for 

 first year, but ashes did for second. 



It is not to be supposed that the same result would follow 

 from all soils. These experiments show the effect upon this 

 soil and location, and may be useful in making comparisons and 

 forming a judgment for each one's own lands.
