 truth concerning it, the addition of cane sugar, without notice to that effect upon the label, is calculated to deceive and should not be practiced. There is no objection of any kind to the use of cane sugar in the canning of pineapples if the label indicates that this has been done. On the other hand there is no reason why the addition of sugar should be practiced. The pineapples are bought and consumed for their natural flavor, and not on account of the added sugar which they may contain. In the canning of pineapples it is just as easy to secure complete sterilization in their own juice as it is to secure it with the added sirup. In practice, however, it is more convenient after filling the cans with the pieces of pines to add a sugar sirup to fill up the spaces than to secure sterilization by the application of heat alone, which would not cause a sufficient quantity of juice to exude to fill up the interstices of the cans, and they, therefore, would be partially empty.

Canned Pineapples.—There is a very large trade in this country in canned pineapples imported from Singapore and the Straits Settlements and the Bahamas. The pines are usually canned with the addition of sugar, and those that come to our ports are as a rule sweetened only with cane sugar.

A large number of analyses has been made of these canned pineapples in the Bureau of Chemistry and the general data which were secured are presented below:

Canned pineapples from Singapore, average, maximum, and minimum composition:

 -++-+++-      |   |    |  |      | -++-+++-             |Percent.| Percent.|Percent.|Percent.|Percent. Average,    |  20.15   |   17.90   |   .46    |   .28    |   .30 Maximum,    |  25.30   |   25.10   |   .60    |   .36    |   .43 Minimum,    |  18.18   |   14.87   |   .39    |   .21    |   .16 -++-+++-

The above data show that it is possible to compute the average quantity of sugar which is added in the preparation of the sample. If we assume in round numbers that the natural pine contains 12 percent of sugar, we find that approximately eight pounds per hundred of fruit have been added in the preparation of the pines from Singapore.

Below is found the average, maximum, and minimum composition of ten samples of canned pineapples from the Straits Settlements:
