Dear Don,according to the EDNOTE. Yes, it was for "delectation" -- as is perhaps too much of NABOKV-L stuff....  but what kind of  delectation would be "too much "? 
 
I just received SK´s and Sandy Klein´s  delightful comments on Doyle´s Ray Jr.  and the demolished structure with hidden treasures. And yet, while perusing Lolita I discovered that  "Nymphets do not occur in polar regions".
HH adds: " I left my betters the task of analyzing glacial drifts, drumlins, and gremlins, and kremlins, and for a time tried to jot down what I fondly thought were "reactions" (I noticed, for instance, that dreams under the midnight sun tended to be highly colored, and this my friend the photographer confirmed)" (ch.9)
Could the arctic pictures taken by Bert (Bert!) confirm our fabulist´s story?
