I have just finished transcribing this document which is in the Dorset History Centre catalogue reference Q/S/M/1/9 page 414.

It describes the roads which Joseph, Lord Milton had a writ issued by Chancery, to move. These road closures spelled the end of the old town of Milton Abbas as a thriving community. Now the town was no longer on the main through route, and was subsequently bypassed by the turnpike which went from Blandford to Dorchester through Milborne St Andrew.

It should be possible to locate the old roads on a modern map. Anyone fancy doing that?

this is a literal transcription:

“….beginning at the Foot of Saint Catherines Hill opposite to the said Lord Miltons Stable and from thence to the Top of the Hill where another Road Branches out of it to the Eastward leading to Beer Regis in your County and from thence Northward through the same Field called Saint Catherines Hill to a Gate leading into Higher Haydon Field and from such Gate through the South East End of Higher Haydon Field to a Gate leading into Houghton Common called Houghton Down Gate having the Lands of the said Lord Milton on both sides thereof and which said Road from the Foot of Saint Catherines Hill to Houghton Down Gate aforesaid measures in length Five Thousand six Hundred and Fifty four Feet and in breadth Twenty Feet or thereabouts Also the said Road which branches off from the before mention Road on the Top of Saint Catherines Hill aforesaid and from thence Eastward through the said Field called Saint Catherines Hill leading to Beer Regis aforesaid to a Gate which opens into Hoggen Down having the Lands of the said Lord Milton on both sides thereof and which said Road measures in length from the Top of Saint Catherines Hill to the gate which opens into Hoggen Down aforesaid two Thousand four Hundred and one Feet and in Breadth Twenty Feet or thereabouts Also another Road lying in the Parish of Milton Abbas aforesaid beginning at the Cross Roads on the Top of White Hill and from thence down the Hill called White Hill Road to the bottom thereof where another Road comes into the same called Hollow Way having the Lands of the said Lord Milton on both Sides thereof and which said Road measures in Length One Thousand seven Hundred and Forty two feet and in breadth Sixty Feet or thereabouts Also the said Road called the Holoway lying in the Parish of Milton Abbas aforesaid beginning at the Bottom of White Hill aforesaid and ending where it falls into the Cross Lane or Road leading from Milton Abbas Pound to the Parish of Dewlish in your County having the Lands of the said Lord Milton on both sides thereof and which said Road measures in length One Thousand One Hundred and Eighty Feet and in breadth Forty Feet or thereabouts”
