I found many Cicely Fox-Smith poems in the PUNCH magazine, (Charley Noble & Shanteyman uploaded these to OLDPOETRY.COM) but there was just one which defied the harvest.
Libraries bind such magazines into volumes, and if one is lucky, there will be a volume index too. This is the case with Punch. All good and well! But from time to time, Punch published additional "specials". It turns out that there is a CFS poem in one of these specials; however, it was not incorporated into the binding of the 2 libraries I used (Nottingham & Bradford, UK)for my research.

So, my challenge is, for any librarian amongst our number, or members who have ready access to a main library to see if your library archived in some way (binding or micro-fische)the 1950 Punch ALMANACK which contains the CFS poem "The Best Days". Be aware there are 2 volumes for each year. Any takers?
Or perhaps someone knows another way!
