aS In consequence of the aa economical situation an approximately correct 
estimate of the 1915 production of rose oil is not to be thought of. Interested parties 
; seem to be of opinion that the crop will be 20 to 30 per cent. below the one of the 
— year before. But this decrease is not likely to produce a rise in prices, seeing that 
there are still old stocks on hand, and that business, as may be expected, is anything 
- _ but flourishing. So far prices have not been fixed. Some producers and dealers, in 
E avant of money, have sold small parcels but the prices obtained by them cannot be _ 
looked upon as forming a basis for the market value. At the present time the price an 
_ for genuine, pure oil is nominally -4 1500.— per kilo. | ie 2 
_ __In connexion with this report we would like to give a few particulars from a 
- report published elsewhere on Bulgarian rose cultivation in 1914, according to which 
the cool weather of the early part of summer delayed florescence, and in consequence 
_ the crop and the distillation of the oil*). In some of the producing districts, such as 
_ f.t. Kalofer, the rose plantations suffered from hail and produced an inferior crop of — a4 
blossoms. In almost all the other districts, however, the crop, according to official — 2 
reports, has been very good and may be said to have been better than the previous crop — 
_ both as regards quantity as well as quality. In Kazanlik and Schipka f.7., an average 
of 17 kilos of white and 12 kilos of red blossoms were required to produce one miscal 
~ of oil, in Brezovo 10 to 11 kilos, results which compare favourably with the best years. 
“ In Tchirpan one dekare yielded 270 kilos of blossoms: in this instance 10 to 12 kilos: = 
of blossoms were required to produce one miscal of rose oil. pee
