Size grades for ripe olives, F. T. Bioletti {Calif omm Sta. Bill. 26S {1916), 

 pp. 215-227, figs. 2). — In this bulletin the author discusses the uses and methods 

 of sizing olives, presents data showing a great variation in the present practice 

 of sizing, and describes some work conducted with a view to establishing 

 a basis for a common standard. 



An attempt was made to discover the relation between diameter and number 

 of olives per pound. This relation, however, was found to vary according to 

 the shape of the olive and its specific gravity. From a large number of weigh- 

 ings and measurements a factor has been determined for each of several of 

 the principal pickling olives from which the number of olives to the pound for 

 the various sizes may be determined. This factor differs for each variety of 

 different shape, and varies especially with the change in ratio between length 

 and thickness of the olive. Various systems of size grading with reference to 

 diameter are compared and a grade based on a difference in diameter of 88 

 per cent is proposed. In this system of grading each grade is almost exactly 

 88 per cent of the average diameter of the next larger grade and weighs G8 

 per cent as much per pound. The number of olives to the pound wouhl bo 

 inversely proportionate to the weight and the number for each grade would 

 be 68 per cent of the next smaller grade.

 together with an outline of experiments in budding and gi-afting cacao that 

 are being conducted on an estate in Trinidad.
