Weight of Oranges. — The weight of a box of oranges 

 varies in each season, in the months of the same season, in 

 different varieties, and in the different sizes of each variety. 

 The difference in weight is caused by many circumstances. In 

 some seasons climatic conditions are such as to build the tissues 

 solid and firm. The plant seems to have an added power to 

 construct the heavy sugar compounds and build its tissues 

 compact and with more than its usual weight. In arriving at 

 the weight of oranges all of these conditions have to be con- 

 sidered. An average season is when there is a continuous and 

 even distribution of heat units during the summer months, 

 with no frost to break the inner tissues of the orange, causing 

 both evaporation of its juices and reabsorption, preventing the 

 tree giving and the orange appropriating the starch-building 

 compounds from the injured and unelaborated sap. There are 

 also local conditions — as soil, nearness to the ocean, altitude, 

 and the general slope of the orange area, as to the north, east, 

 south, or west — to which may be added those personal condi- 

 tions of irrigation, fertilization, and cultivation. 



Taking the season of 1895 as an average season, and the 

 orange growths of March, April, May, and June, produced on 

 the terrace lands of Colton, the average net weights of packed 

 oranges in the standard orange box were as follows:
