At his return to London I went with him to the daughters of Mr. Mathew, who shewed him their father's papers; sc. draughts, modells, copper-plate of the mappe of the Thames, Acts of Parliament, and Bills prepared to be enacted, &c.; as many as did fill a big portmantue. He proposed the buying of them to the R. Societie, and tooke the heads of them, and gave them an abstract of them. The papers, &c. were afterwards brought to. the R. Societie; the price demanded for all was but five pounds (the plate of the mappe did cost 8li.) The R. Societie liked the designe; but they would neither undertake the businesse nor buy the papers. So that noble knight, Sir James Shaen, R.S.S., who was then present, slipt five guineas into J. Collins's hand to give to the poor gentlewomen, and so immediately became master of these rarities. There were at the Societie at the same time three aldermen of the city of London (Sir Jo. Laurence, Sir Patient Ward, and …. ….), fellows of the Society, who when they heard that Sir James Shaen had gott the possession of them were extremely vex't; and repented (when 'twas too late) that they had overslipped such an opportunity: then they would have given 30li. This undertaking had been indeed most proper for the hon{oura}ble city of London.
Jo. Collins writt a good discourse of this journey, and of the feazability, and a computation of the chardge. Quaere, whether he left a copie with the R. Society. Mr. Win, mathematicall instrument maker in Chancery-lane, had all his papers, and amongst many others is to be found this.
I have been the more full in this account, because if ever it shall happen that any publick-spirited men shall arise to carry on such a usefull work, they may know in whose hands the papers that were so well considered heretofore are now lodged.
Sir Jonas Moore, Surveyor of the Ordinance, told me that when the Duke of York sent him to survey the manor of Dauntesey, formerly belonging to Sir Jo. Danvers, he did then take a survey of this designe, and said that it is feazable; but his opinion was that the best way would be to make a cutt by Wotton Bassett, and that the King himselfe should undertake it, for they must cutt through a hill by Wotton-Basset; and that in time it might quit cost. As I remember, he told me that forty thousand pounds would doe it.
But I thinke, Jo. Collins sayes in his papers, that the cutt from
Ashton-Kains to Charleton may bee made for three thousand pounds.
[Some of the above facts are more briefly stated by Aubrey in his "Description of North Wiltshire" (printed by Sir Thomas Phillipps, Bart.) They are however sufficiently interesting to be inserted here; and they clearly shew that, notwithstanding Aubrey's credulity and love of theory, he was fully sensible of the beneficial results to be expected from increased facilities of conveyance and locomotion. On this point indeed he and his friends, Mr. Mathew and Mr. Collins, were more than a century in advance of their contemporaries, for it was not till after the year 1783 that Wiltshire began to profit by the formation of canals.
Sanctioned by the approval of King Charles the Second, for which, as above stated, he was indebted to Aubrey, Francis Mathew published an explanation of his project for the junction of the Thames with the Bristol Avon. This work, which advocated similar canals in other parts of the country, bears the following title: "A Mediterranean Passage by water from London to Bristol, and from Lynn to Yarmouth, and so consequently to the city of York, for the great advancement of trade." (Lond. 1670, 4to.) An extract from this scarce volume is transcribed by Aubrey into the Royal Society's MS. of his own work; and a copy of Mr. Mathew's map, which illustrated it, is also there inserted.
The liberality of Sir James Shaen in the purchase of Mathew's papers, and the apathy of the London aldermen, until too late to secure them, are amusingly described. Similar instances of civic meanness are not wanting in the present day; indeed the indifference of corporate authorities to scientific topics is strikingly illustrated by the fact that the Royal Society has not at present enrolled upon its list of Fellows a single member of the corporation of London; whereas in Aubrey's time there were no less than three.
The short canal projected in the seventeenth century to connect the Thames and Avon has never been executed: subsequent speculators having found that the wants and necessities of the country could be better supplied by other and longer lines of water communication. Hence we have the Thames and Severn Canal, from Lechlade to Stroud, commenced in 1783; the Kennet and Avon Canal, from Newbury to Bath, begun in 1796; and the Wilts and Berks Canal (1801), from Abingdon to a point on the last mentioned canal between Devizes and Bradford.- J.

Mdm.-The best and cheapest way of making a canal is by ploughing; which method ought to be applied for the cheaper making the cutt between the two rivers of Thames and Avon. The same way serves for making descents in a garden on the side of a hill.- See …… Castello della Currenti del Acquo, 4to; which may be of use for this undertaking.
