sun-and Ander ordinary garden conditions. Others,, like Brasil., must

have compete shade and a very humid atmosphere.

LOCATION. To secure the best results from Kost of the

varieties and to secureia luxurious development of highly prized

varieties., it is necessary to have a l-ocation wher-e-they are shaded

direction.The-medium growing varieties may a planted 2 fingersdeep and

1 mulching of this kind will not only keep the soil cool but also prevents:

..excessive drying out. Cultivation with a rake is much better than with

a hoe. Previous to cultivation the mulch should be removed and imme-

diately afterwards returned

"Care of the Rhizomes. With the approach of mmnhim .cool dry

weather, the rhizomes begin to mature, and the leaves dry up and loose

their brilliant color. They should then be dug and Allowed to dry

off in the shade for a week or two. Then they may be preserved in dry

sand, dry terrigo Or dry moss. During the latter part of September of

earlier part of October will be found to be a good time for preparing

-the new beds. The rhizomes ma then be separated into units, leaving

aOhlad'with each pmim part. The large rhizomes may be cut very much as

Irish potatoes are cut for planting, *leaving a well developed eye in

each piece.
