PHOSPHATKOFLIME. 61 



least. In the course of a year, if the ore continues to be worked, 

 several tons of it might be procured. In using it, it should be 

 reduced to an impalpable powder. 



The color of this phosphate is red or reddish. It sometimes 

 appears in large crystals upon the walls of the vein, but it is so 

 extremely brittle that it will be very difficult to procure it in a 

 good form for the cabinet ; still, it is an interesting variety. 



Another locality of phosphate of lime deserving of the atten- 

 tion of the agriculturist, is that of the Sandford ore bed in Moria 

 or Westport. It is washed out of the ore in the same way as the 

 former. Its color is a duller red than the former, or rather brown, 

 and is always in small grains, and appears somewhat like the flesh- 

 colored feldspar. 



In addition to the above localities of phosphate of lime, one 

 other is deserving of notice, which we had forgotten when we 

 commenced our notice of the preceding. It is at Crown Point, 

 and th^ mineral is known as the eupyrchroite. We discovered its 

 locality while engaged in the survey, and as the external characters 

 are so dissimilar to phosphate of lime, we considered it a new 

 mineral substance. Our experiments at the time showed it to be 

 a phosphate, but we conjectured that it contained another sub- 

 stance in combination. We still entertain this opinion. But the 

 analysis of Dr. Beck shows that phosphate of lime enters largely 

 into its composition ; and as it forms a vein in the rock more than 

 a foot wide, it is possible it may be of some importance to the 

 farmer. It is a dull green, and fibrous and obscurely mamillary, 

 or in the form of segments of a sphere. This substance is inter- 

 mixed with silex in little masses in the interior, and on that account 

 will not pulverize so easily as it usually does. We have not ex- 

 amined it, however, with the view of determining how much this 

 locality can furnish at a reasonable expense. At the time we dis- 

 covered it, we considered it rather in the light of a trap dyke, or 

 an earthy vein ; it was concealed, however, partly by soil, and 

 hence we may be deceived as to its wndth, nature of the deposit, 

 as well as to its extent.
