To quickly assess the difficulty of the text, read a short excerpt:
The milky juice, which exudes copiously from breaks in the skin of the fruits up to the time when the fruits can be cut for ripening in tlie house, contains a di- gestive principle that is fatal to the eggs and larvae of the fly. This juice protects the fruits from infes- tation when imma- ture. But as the fruits become over- ripe, and also unfit for the table, the juice flows less abundantly from breaks in the skin made by the fly when she attempts to lay her eggs, and the eggs which she then ...lays can mature. As many as 205 fhes have been reared from sin- gle overripe fruits. So while the papaya is a host fruit, it is practically never in- fested until too ripe or otherwise unfit for the table. AVOCADOS. With the exception of one or two early varieties, the infesta- tion of the avocado is so obsciu"e that the general belief prevails in Honolulu that this fruit is free from at- tack. The Guate- mala, or nutmeg, variety is the only one free from attack when growing uninjured. Theskinof allother varieties, whether tliinorof usual tough- ness, can be punctured by the adult fly, as proved by many examinations of fruits.
