to execute the said design: Those Gentlemen, which do constitute the
_Commitee_ for considering of _Agriculture_, and the _History_ and
_Improvement_ thereof, have begun their work with drawing up certain {92}

already obtained and used in these Kingdoms; whereby, besides the aid which
by this means will be given to the general End of collecting the
aforementioned _History_, every place will be advantaged by the helps, that
are found in any, and occasion ministred to consider, what improvements may
be further made in this whole matter. Now to the End, that those
_Enquiries_ may be the more universally known, and those who are skilful in
Husbandry, publickly invited to impart their knowledge herein, for the
_common_ benefit of their Countrey, it hath been thought fit to publish the
_effect_ of them in Print, and withal to desire that what such persons
