percolate into it. As the slopes are very thoroughly 

 manured in the autumn, before the snow falls, and as the 

 goats wander about here, the danger, as soon as the melting 

 snow keeps the ground soaked, is very great. There is a 

 second danger from the fine particles in the water, and 

 ao-ain the amount of magnesia should be examined, as it will 

 from some springs be considerable. Filtering the water 

 would be a great advantage, but could not affect the organic 

 impurities. Upon making this discovery I at once gave up 

 drinking any water, and the results showed that I was at 

 last upon the right track. 



Being in an hotel which calls itself a Curhaus, and where 

 a doctor has resided for many years, I had not thought 

 that such an unsatisfactory, primitive, and dangerous method 

 of collecting the water was possible, and though probably 

 no other hotel obtains its supply in the same way (in fact 

 most will now be furnished from a water supply collected 

 in the Fluela valley some miles away), yet all should be 

 examined; and the object of what I am saying, is to urge 

 the English doctors who send patients here to use their 

 influence to have an officer of health appointed, with the 

 right to examine all sanitary questions. 



Davos Platz has now become a town producing at times 

 a veil of smoke, which in an English town we should call 

 a fog, and this, if scientific methods were employed, could 

 be much reduced. I am in a position to say that the 

 sanitary arrangements in some of the hotels require entirely 

 changing to be suitable for a place which has grown so 

 rapidly, and with the possibility of frozen drainage, these 

 and all other sanitary questions should be periodically 

 examined by a competent official.
