a Tr-avdler o?i the. Glacier of Buet. 117 



Thefc precepts are addrefTed, more or lefs directly, to all 

 travellers who may be defirous of traverfing the mountains; 

 but T (hall add a tew words to thofe who are philofophers or 

 naturaliits, and to the amateurs of lithology in particular. 

 The latter have frequently experienced the inconvenience of 

 having nothing but their pockets to contain the fpeciinens of 

 rock which they detach with a hammer : thefe are foon filled, 

 and harafs the traveller by their fwinging movement. I 

 fupply this deficiency, with advantage, in the following 

 manner : 



To a pretty broad leather belt I have adapted a loop of 

 the fame material, placed in an inclined pofition, to receive 

 my hammer, nearly in the fame manner as the Turks carry 

 their poniards. On the other fide is a fmall pocket, which 

 contains a bottle of acid in a wooden cafe, a piece of ileel 

 for ftriking fire, &c. This belt or girdle forms the upper 

 part of an apron of very thin leather, which, when letdown, 

 would cover the knee, but which, when tucked up on each 

 fide, forms a large horizontal pocket before, open at the top, 

 and fupported in the middle by a thong fhaped like an in- 

 verted Y; the two branches of which are fewed to the girdle, 

 and pafs round the apron below. The tail of the Y is turned 

 up before, and is buckled to the bandolier with which [ 

 carry my barometer. The ftones which I put into this 

 pocket being difpofed, as it were, around the centre of gra- 

 vity of the body, and being fupported in parb by the (haul* 

 derSj on account of the thong which envelops the apron, 

 occafiun no inconvenience. I thus have them all under 

 nay eve, and at hand when I wifli to fubftitute one fpecimea 

 for another; and they experience no agitation, and do not 

 rub again ft each other as they do in the pockets. 



To the fame girdle, on one fide, are fufpended, by fteel 

 hook*, one of Ilamfdeu's fextants of three inches radius, 

 which gives even the minutes of a degree ; an inftrument 

 exceedingly convenient for naeafuring angles. On the other 

 fide is fufpended an artificial horizon, with a fpirit level for 

 taking heights. The box of this inftrument I difpofe in 

 fuch a manner that it feryes me for a Hand when neceffary* 

 being fupported by a liatl" thai opens at bottom with three 



feci;
