The foregoing rates are for ore with 0'17 to 018 per cent, phosphorus. 
With 0*14 to 0-17 per cent, phosphorus the price was 1 cent per unit of 
manganese higher ; and below 0'14 per cent, phosphorus 2 cents per 
unit of manganese higher. With O'lS to 0-20 per cent, phosphorus the 
price per unit of manganese was 1 cent lower than the foregoing prices. 
The analyses were made on a sample dried at 212° F., and the mois- 
ture in the sample deducted from weights. The foregoing information 
is taken from the section on manganese by J. D. Weeks in the Mineral 
Resources of the United States for 1886, page 208. It will be seen from 
this that in 1886 ore containing 50 per cent, manganese and only O'lO 
per cent, phosphorus would have fetched 27 cents or 13| pence per unit. 
In the following table and d'agram (fig. 23) are given the quota- 
tions — from the Mining Journal, London — for the price per unit of 
manganese, for the first week in January and July of each year since 
1890, for the three grades into which manganese- ores are usually 
divided : —
