The dot is inlended to make the reading easier and the 
various groups clearer, thus : 
0.6381.24.3 indicates that the group 0.6381 belongs to apicul- 
ture and bees, 0.6381.24 indicates the group implements iov working 
in hives and handling bees, and 0.6381.24.3 the group gloves and 
veils. 
In drawing up the index of periodicals, the numbers should 
always be placed in order of magnitude from the lowest to the 
highest, and always considered as decimals, thus: ».24 is smaller 
and should be placed before )>.245 and this again before ». 27. 
When an article or memorandum includes several subjects 
belonging to various classifying number.s, all these numbers should 
be separated by the sign +, thus one would mark ». 17 + ».953 
for a memorandum dealing with sulla (Flora) and the quality of 
honey gathered from it (Honey). 
These articles would appear twice in the index with each of 
the two respective numbers, as if the article had been published 
once with one number and once with the other. 
Besides when compiling an index the title of the article or 
memorandum .should be written after the classifying number, be- 
cause this number only would be used, so that one might find 
what is required at a glance, without having to read so many 
titles as is now necessary, which ha\o not even a remote con- 
nection with what one is seeking. After the title, naturally, comes 
the page as usaal. 
It would be of the greatest value to bee-keepers, if some 
one would cjmpile such an index of all periodicals on apiculture 
of the past. This would aOord great value to all the contents of 
the periodicals, because with such a work, not of many pages, 
the usefulness of those contents would become much greater, 
being acces.sible to even a not very patient student, who could, 
at a glance, pick out what would be useful for his studies. 
It is well to nolo here that the classifying number in the i 
various periodicals is not only useful for rapidly finding in the I 
index the subject required, but also for any one wishing to read 
the extracts generally written without a title, the above menti-| 
oned number serving as a concise title, after a little practice has 
been acquired in the use of the tables. For instance if an extract 
be marked (.8), one would at once know that the article so marked 
treats of the formation of bee colonies.
