From Edward Fry   24 October 1881

Sir,

I need not I presume apologize for calling your attention to a fact about worms.

On my lawn here there stand two large mulberry trees, both of which shed their fruit in considerable quantities on the grass—¹ The worms use these fallen mulberries to stop the mouth of their burrows with.—² The fruit is so to speak worked into the cast—the heap being thrown up around & at the side of the mulberry. Whether the worms draw the mulberries to their holes or only use them as stoppers when they hit them by accident (as under one of the trees they would often do) I do not know.—and as the mulberries are nearly over, can hardly ascertain this year.

Your obed Serv^t | Edw: Fry
