Marblehead Squash
This squash, as a rule, is characterized by a shell of a more flinty hardness than the Hubbard. It is usually thicker and flatter at the top. It has a greater specific gravity. The flesh is of rather a lighter color than the Hubbard, while its combination, in good specimens, of sweetness, dryness and delicious flavor is something really remarkable. Its outer color is a light blue. Pkt., 5c; oz., 15c; lb., by exp., $1.00; lb., $1.15.
