 50 gallons Water. 



First, the bleaching powder should be dissolved in a small 

 quantity of water three or four gallons. Mixture should be 

 stirred until the powder is dissolved. In a separate container, 

 holding a few gallons of water, dissolve the Sal Soda. Mix the 

 two solutions and stir well, and allow it to stand until the Car- 

 bonate of Lime settles in the bottom. The clear liquid should 

 be drawn off and diluted with water so as to make fifty gallons. 

 The nuts are placed in dipping boxes, are immersed in the fluid, 

 and then one and one-fourth pounds of 50 per cent Sulphuric 

 Acid is added. The liquid is agitated by raising and lowering 

 the dipper. In from five to ten seconds the nuts should be suf- 

 ficiently bleached and should then be rinsed in clear water and

 The same liquid can be used as long as it gives results. Occa-

As soon as the nuts have been thoroughly dried, they should 

 be graded. Up to the present time, Oregon orchardists have
