aImported: analyzed at this station. 
With the exception of the grape, it seems that the fig draws rather more heavily 
upon the mineral ingredients that will need to be replaced by fertilization than 
do any of the other fruits we have examined, following closely the amounts taken 
up by the grape and fig of foreign growth. As compared with the fig, apricots 
and prunes, like oranges, do not in any case draw nearly so heavily upon the min- 
eral matters. Lemons and plums, however, very nearly approachit. And among 
the figs we note that the White Adriatic stands somewhat above the other figs in 
this respect. As to nitrogen, it is readily seen that among our fruits the figs, on 
the whole, draw decidedly the highest amount and are quite like those of foreign 
production in this regard. Here again the White Adriatic appears to lead. 
Potash.—In the ashes of the fig, as in the prune, apricot, orange, and lemon, we 
find potash to be the leading ingredient, amounting to about three-fifths of the 
whole ash. From the partial ash analysis, given above, of the imported Smyrna 
fig, we find the potash to be four-fifths as much as is contained in the ashes of figs 
of California growth. 
TABLE OF SOIL ANALYSES. 
The comparison of the analyses of the Asia Minor soils with those from this 
State shows very strikingly the richness in phosphoric acid of the former over the 
latter. The lowest percentage of this ingredient in the Asia Minor soils, 0.29 
found in soil B, is more than one and one-third times as much as the highest, 0.22 
shown in soil No. 1466, of the California soils. and the average, 0.32 per cent, of 
the three Smyrna soils is almost exactly four times the average for all California 
soils examined (about 200 in number) and nearly three times the figure 0.113, 
denoting the average of phosphoric acid for 466 soils of the humid region (east 
of the Rocky Mountains) of the United States. 
With reference to lime, the average for the Asia Minor soils is 2.60 as against 1.08 
for California. The figures 0.690 for Asia Minor and 0.644 for California, repre-
