^Browne, Edward Granville (1893). A Year Amongst the Persians. London: A & C Black. "This Dari dialect is only used by the guebres amongst themselves, and all of them, so far as I know, speak Persian as well. When they speak their own dialect, even a Yezdi Musulman cannot understand what they are saying, or can only understand it very imperfectly. It is for this reason that the Zoroastrians cherish their Dari, and are somewhat unwilling to teach it to a stranger...To me they were as a rule ready enough to impart information about it; though when I tried to get old Jamshid the gardener to tell me more about it, he excused himself, saying that knowledge of it could be of no possible use to me."
