The melons covered in the book range from the true cantaloupe to muskmelons (what Americans call cantaloupe) to casabas to Asian melons (not sweet like those to which Americans are accustomed) to those that aren't tasty (but are valued for other reasons) to every color flesh and seed, size and shape of watermelon under the sun!
How about a melon to scent a person or a room, a melon to stand in for a cucumber in a salad (bitterfree, crisper, and will set fruit all summer long), a melon that looks for all the world like a winter squash, a bi-colored-flesh watermelon, or a watermelon whose skin turns a bright yellow when it is ripe?
These are the Queen Anne's pocket melon or the D'Alger melon, the Snake melons, the Prescott Fond Blanc melon, the Colorado Striped Tarahumara watermelon, and the Golden Midget watermelon.
Don't have room to grow your own melons? Then the pages about how to select a melon, even at market, will be invaluable--already I have been able to improve my chances of coming home with a riper melon from the store.
I have one tiny complaint about the content of the book: there are several varieties that are listed with "Seed Source: None". I assume these melons that are not available from commercial seed sources are available among the Seed Savers Exchange organization members, but that is never mentioned.
My other complaint about the book is technical: it's not what most of us would consider a "hardback". It has a firm cover, but it's not a hardback in the traditional textbook sense.
All in all, a very lovely book, one that makes you wish you had 10 acres in which to just grow melons. It has been an engrossing read and re-read, an indispensable book in planning our future forays into melon-growing.
