NOTE. — Xo. I contains about 83 i)er cent slaked lime vritb. few per cent caxistic magnesia 

 and carbonate of lime; it will pass a 60 mesh sieve; quoted ^.00 per ton, bulk,_ f. o. b.. West 

 Stockbridge. Average freight rates to Massachusetts points §2.00 per ton. Xos. 11 and III 

 carry over SO per cent slaked lime with small amount caustic magnesia and carbonate lime. 

 It is sufficiently fine to be used in a fertilizer diill; supply said to be limited as it is the residue 

 from the slaked Hme which will not float in an air blast. Quoted S2.00 per ton, bulk, f. o. b. 

 West Stockbridge. Xo. IV is unscreened slaked lime composed of about &1 per cent slaked 

 lime and 11 per cent caustic magnesia, the whole fine enough for drilling. Quoted $3.00 per 

 ton, bulk, f. o. b., car lots. West Stockbridge. Xo. V is refuse lime that has been thrown in a

XOTE. — X^o. I. Lime ashes will vary widely in comi>osition. At SS.OO to S9.00 per ton

 Wood ashes of late years vary so widely in composition and run so low in potash as to gi\e 

 the impression that few shipments are unleached but rather a product which has been either
