A Defcription 
Of , the Stone §>tiarry near Maeftrfch 3 commumcated by an 
Obferving Per/on^ converfant in that Country. 
T Here is an excellent Qiiarry, within Canon- (hot o( Maef- 
trjch^ upon the very brink of the River Mafe^ lying in a 
Hill, where there are about 2 5 fathoms of Fvock and Earth o- 
ver head 5 th^e length of the Hill being of feme miles extend- 
ing along the River towards Liege 5 fcituate on the fame Ri-^ 
ver^ and near il/^e/?r/VA having in breadth 5 fOTe4or|of a 
milej but fome more, farther off* This Quarry hath one Entry 
towards theRiverj where Carts can pafs with great eafe , and . 
unload the Stones upon the brink of the River 5 the Quarry 
within lying paralfel to the Horizon or level, (which is a great 
advantage) and elevated but very little above the River. 
This fame Quarry, which hath, well nighj undermin^d the 
whole Hilljaffords opeof the moft furpri^iing Profpeils, when ' 
well lighted with many Torches, that one can imagine. For, 
there are thoufand^ of fquare Pillars in large level WalkSj and \ 
thole almoft every where, above 2G, and in fome places,niany 
more foot high, and all wrought with fo much neatnefs and re- 
gularity, that one would thinkj it had been made rather with * 
curious Workmanfliip for an under-ground Pallacejthan that 
thofe Pillars and Galleries were made by Quarriers, that did i 
it only for getting Stone to build above-ground^ 
This Quarry ferveth the People^ that live thereabout , fbr 
a kind of impregnable Retreat^when Armies march that way. 
For, being acquainted with all the ways in k , they carry mto 
it whatfbever they would haveiafe , as well their Horfe and 
Cattelj as their Moveable furnkure^, tilL the danger be over ^ /
