Does someone know...

The other day I was asked how to read a haiku of Lafcadio Hearn;

Nadeshiko ni
Chocho shiroshi
Tare no kon?

It is the haiku that Hearn published in 1915.
I haven't checked the original Japanese.
As for "kon", it means "soul". So my friend wonders it might be better to be read "tama" of tamashii=soul instead of kon.
