(a.) Dissolve the bluestone in 10 gallons of water by placing it in a

 separate the grit, and bring the milk of lime to 10 gallons. Mix a and b, 

 and make up to 22 gallons. Use only wooden or earthenware vessels. 

 When the foliage is out, use the half strength mixture by diluting in double 

 the volume of water. To determine if the mixture is safe to use on tender 

 foliage, insert a new nail or the blade of a penknife for at least half a 

 minute ; if copper is deposited on the steel, lime must be added.
