to the eye,
by mere _rote_. What a waste of time to attempt to re-arrange it in
order to learn it more easily. Yet such a Series can be learned by
correlating the words together in a very short time, thus:--

_Ad_ ... addition ... front addition ... _ante_-room....
_Ante_ ... antecedent ... _con_sequent....
_Con_ ... converse ... _in_verse....
_In_ ...
_Inter_ ... interject ... _ob_ject....
_Ob_ ... obligation ... _post_poned obligation....
_Post_ ... post-office ... _pre_payments....
_Pre_ ... predilection ... _pro_pensity....
_Pro_ ... produce ... soil products ... _sub_soil....
_Sub_ ... subordinate actor ... _Super_.

And, similarly, we can deal with any Series in =Grammar=, or elsewhere.

1. Do my pupils ever find any difficulty in correlating the series
as they may find it?
2. What training must they have in order to do so?
3. Is any time misspent in trying to discover a non-existing
relation?
4. What are the eleven Latin prepositions here given?
5. How are they usually learned?
6. Is time gained thereby?

(2) The other kind of Series is where the words, facts, or things _must_
be memorised as given. The seven primary colours are given as they occur
in nature, thus:--Violet, Indigo, Blue, Green, Yellow, Orange, Red. The
unconscionable word VIBGYOR has been given as a means, through the
initial letters of the colour words, to enable us to remember those
words, and ROYGBIV to enable us to remember the Series backwards. To
such a pass are educators driven when they lack my Universal Method of
cementing Extremes. We know the Series both ways if we Correlate the
words, thus:

_Violet_ ... let go ...
_Indigo_ ... indigestion ... "blues" ...
_Blue_ ... blue sea ... sea green ...
_Green_ ... green corn ... ripe corn ...
_Yellow_ ... yellow fruit ...
_Orange_ ... orangemen ... fights ... blood split ... blood-red ...
_Red_.

ORDER OF THE ENGLISH SOVEREIGNS.

The true Method of learning the Order and Dates of the English
Sovereigns, as of the American Presidents, or of any other list of
Rulers, is to deal with them only in the course of reading. When met
with in History, all the facts are before the reader, and, if he fails
to hold the _order of succession_ clearly in mind in any case, he can
easily correlate the Names together. And if he fails to retain some of
the dates, he can readily make forgetfulness impossible by
