142 EXPERIMENT STATION RECORD. 



pressing the mass of pulp, pits, skius, oil, and water was divided into 

 251b. packages and wrapped in sail dotli, wliieh was found clieaper- 

 and preferable to tlie grass mats used in Europe. The mingled oil and 

 water from the pressing were separated by an apparatus devised at the 

 station, being allowed to flow into a tank about 4 ft. liigh and 2 ft. in 

 diameter. The inlet was near the bottom, and just below it a series 

 of jets of water washed impurities out of the oil, which rose to the top 

 and was drawn ott' by a stopcock, the height of the water being regu- 

 lated by another stopcock and an escape pipe. The oil was cLarified by 

 filtration, experiments being made with cotton batting, glass wool, 

 asbestos, and filter paper. Only the last was found to be adai)ted, 

 and frequently two flltrations were necessary. 



The same variety was found to vary in different localities in regard 

 to the proportion of flesh and percentage of oil, and tables are given 

 showing the analyses. Rubra varied the most in amount of oil, there 

 being over 20 per cent difference between the maximum and minimum 

 found. 



Mission, Manzanillo, and Nevadillo Blanco are recommended as oil 

 producers, and Redding Picholine is considered unworthy of the place it 

 has in the plantations, as its fruit is small and "greasy" aiul possesses 

 large i^its. 



The investigations are to be continued another year.

 7 recent varieties of apples aiul 3 of pears, with brief notes on the productiveness 

 of 23 other varieties of pears, and mention of an unsatisfactory plum crop, in which 

 the fruit dropped from some undetermined cause. 



Small fruitn (pp. llli-12i). — Notes and tabulated data for 23 varieties of strawber- 

 ries, Greenville, Crescent, Shuster Gem, and Van Deman giving the highest yields ; 

 and for 13 varieties of blackberries, Eldorado, Early Cluster-, and Early Harvest pro- 

 ducing the largest crops. No raspberries were fruited, but brief notes are given on 

 4 varieties of gooseberries and 2 of grapes. 



Vcgvtahles (pp. 122-129). — Notes and tabulated data for 4 varieties of asparagus, 18 

 of beans, 13 of sweet corn, 14 of peas, and 23 of tomatoes. The "Chinese potato" 

 {Dioncorea hatatas) is being tested, and has produced a fair crop of tubers.
