MAY IT PLEASE YOUR GR AC E, 
OUR Grace’s kind Acceptance of two former 
Editions of this Work, has emboldened me to 
lay this at Your Grace’s Feet, as a public Ac- 
knowledgment of the many ufeful Obfervations 
and Inftru&ions, which Your Grace has at feveral 
Times communicated to me for its Improvement. 
If I have been fo happy as to employ them in fuch manner, as to 
merit Your Grace’s Approbation, I lhall have lefs Reafbn to doubt 
that of the Public ; fince the moft fkilful Perfons in this ufeful Branch 
of Science, pay the higheft Regard to Your Grace’s Judgment. 
The many Improvements which Your Grace is annually making 
fo happily upon Your various Eftates, fufficiently demonftrate Your 
Grace’s fuperior Judgment ; but more particularly in a Country 
almoft deftitute of Timber: Where, if Your Grace continues 
planting, fo ardently as for feveral Years paft, the whole Face of 
the Country will be much altered for the better, and Your Grace’s 
Eftate thereby greatly improved. 
That Your Grace may long live to continue thefe Improvements, 
and to be an Example to others, is the fincere Wifh of 
Your Grace’s 
Moft obedient humble Servant, 
Chelsea,
