PRICKLY PEAR FOR WHITEWASH. 



The use of the sections of the stem — commonly called leaves — 

 of prickl)^ pear (Oputitia spp.) in making whitewash is frequently 

 met with in the West Indies. 



In regard to this matter, a note contained in The Colonizer for 

 November, 1910, drawing attention to a similar employment of 

 the prickly pear in Uruguay, is of some interest. It is stated 

 that the white color of the farm buildings in that state serves for 

 special attraction, even during the wet season. 



The mode of emplo\-ing the ''leaves" is stated to be to slice 

 them, macerate them in water for twenty-four hours, and then 

 to add the lime and mix well. The endurance of whitewash thus 

 made forms a matter for particular comment.
