PROPOSAL FOR THE ACTUAL SURUEY Of all the Counties in ENGLAND and WALES: BY Mr. ADAMS of the Inner-Temple.
THE true measure of a Meridian Line, and the difference of Latitude between the North and South Points thereof, hath been the Enquiry of the best Geographers in all Ages, being the onely means from whence to calculate the true Compass of the Globe of Earth and Water, sup∣posed to be exactly Spherical, and to know how many Miles do make a Degree in any Course, Sea upon a great Circle.
And although the Experiments of our Country-man Mr. Norwood, between York and London, and of Fernelius, Snellius, Riccioli, and the Eminent Picartus beyond Sea, already extant in Print may be thought sufficient on this Subject, yet (the first recommending his Essay to a more correct way of Measure then he used, and all the others dissering in their methods, and disagreeing in the resolution of the thing in Question, and in the adjusting of the Measures of several Nations) the certain truth of this matter doth hitherto remain doubtfull.
The said Mr. Adams for clearing this Important Problem, doth intend to measure a true Meridi••an Line, from the Town of Monmoth, situate upon the Southern Borders of Herefordshire, to the Northern Borders of Cheshire, and to take the exact Latitude of Monmoth, Hereford, Shrewsbury 〈◊〉〈◊〉 Chester, and Warington.
He doth fix upon this part of the Kingdom because (having formerly made, Proposals for 〈◊〉〈◊〉 actual Survey of Shropshire) he already hath the Subscriptions of above one hundred and fifty 〈◊〉〈◊〉 the most considerable Gentlemen in the said County; and the Survey thereof had been completed before now, had not the finishing of his Index Villaris of all the Cities, Marker-Towns, Parishes, Villages and Private Seats in England and Wales, (distinguished by Symbols) and an Alphabe∣tical Table of all the Nobility and Gentry, now ready for the Press, hindred that Work.
And being of opinion, That a true Coasting-Line of the KINGDOM, together with the said Meridi∣an-Line will be a sure foundation to carry on the Survey thereof, especially if such Meridian-Line be continued from Monmoth to the Southern Sea on the Coast of Dorsetshire, and from the Northern part of Cheshire to the Parallel of Barwick: and conceiving that such Survey may be perfected, and large County-Maps engraved within the space of Four Years, to commence from the 25 day of March next 1681. He hopes that the Gentry of this Kingdom will be as ready to encourage this Design, as they were to Subscribe for his Great Map of England, wherein the Computations and Measures of Miles are entred in Figures.
- I. He will, with the assistance of an able Surveyor, measure a much greater Stationary Distance then Picartus did, backward and forward, and, besides the Chain and Wheel, will make use of Pikes screwed together, for the adjusting of such Measure.
- II. That in taking the Angles of Position he will use the best Instruments that can be gotten, and compare the way of Snellius by Pinnules, or Common Sights, with that of Picartus, by Telescopes.
- III. To prove the Truth of such Measure, he doth design, That his Brother, William Adams of Long∣don, in the County of Salop, Esquire, (a person very well known in the said three Counties of Salop, Chester, and Hereford, for his Ability and long Experience in Survey) with the assi∣stance of another able Artist, shall measure a different Station with the same Exactness, and proceed in all things as is before proposed, and that if his Brother measure from North to South, he will measure from South to North.
- IIII. That, in taking the several Latitudes of Places, he will use very large Instruments, and make the Observations double and apart, and proceed therein as he shall be directed by the ablest Mathematicians, whose Advice he desires, in an Experiment of so great Importance and ge∣neral use to all Mankind, but more particularly to the Trading part of the World.
