Remarks on position &c. 





Fixed on dwarf post in the garden, 286. 

 which is somewhat shut in bj the 

 railway embankment ; ground 

 hiUy. 



Very exposed position on a slight 

 slope, but nothing rises more 

 than 5° above the gauge, which 

 is very much weather-worn. 



On level piece of moor, quite ex- 

 posed, but surrounded by a 5-ft. 

 iron hurdle fence 6 ft. square. 

 Glass not accessible. 



On a flat bank on a steep hiU-side 

 facing S.W. Orifice so large 

 as unduly to facihtate evapora- 

 tion. 



In a flat field E. of the reservoir ; 

 very open. When visited the 

 top was not jDrojierly on the 

 cylinder, and much loss must 

 have resulted. 



In a box made of inch-wood, the sides 

 of which being level with the r im of 

 the gauge produce in-splashing. The 

 orifice of the gauge being very large 

 will compensate for this error. Hilly 

 ground. 



On west end of embankment, very 

 exposed position. 



A short distance E. of station, on 

 flattish ground. Hills rise to a 

 considerable height in N.E. 



In field. The box holding this 

 gauge was tilted nearly 5° to 

 S.W., and had been so for some 

 little time ; had it levelled. 



Good position in large flat field. 

 Glass not accessible. 



Near the centre of the moor, slight 

 ridge in W.S.W., but its eleva- 

 tion only 10°. Position good.
