Pierre du Jarric. (Akbar and the Jesuits, Page 75).
Pierre du Jarric, a 16th-17th centuries French priest of the Jesuit order and a professor of philosophy and theology at Bordeaux, travelled to Kashmir in 1596- 1597 as part of Mughal encampment and was first to introduce the western world to Kashmir when his travel letters were published in Antwerp in 1605.
I looked for this description for a long time and finally found it in a footnote to Kalahana's Rajatarangini by Ranjit Pandit. Interestingly the above passage also alludes to the Chinar trees of Kashmir.
