Dear Sms, 
I have very great pleasure to write and inform you, that I took one 
of your Pump Filters to South Africa with me, and I cannot tell you what a 
valuable addition it was to my limited equipment. During the siege of 
Ladysmith I used it every day. The water of the Klip River was thick 
with mud, and the Boers threw dead horses and filth into the river, yet after 
being passed through one of your filters it passed out like crystal, and had 
no disagreeable taste. 
I am glad to certify to the excellence of the filter, 
Yours truly,
