takes some time for the roots to reéstablish themselves in the 
new soil, the ripening will not be completed and the result- 
ing bulbs will be of inferior quality. After the bulbs have 
a they should be taken out of the soil, the leaves cut 
off, and the cleaned bulbs put away in cool, dry storage until 
pets time. It is not necessary to take up the naturalized 
ulbs every year, the hyacinths requiring attention every 
two years, the tulips every three or four years, while the 
others may be left undisturbed even longer. 
The care of the tender bulbs differs somewhat from that 
of the hardy kinds. Gladiolus is one of the best summer- 
blooming bulbs, blooming late in the season and producing 
bright-colored spikes of flowers. The corms are planted five 
to six inches deep, this depth being necessary to furnish sup- 
port for the tender leaves and the heavy spikes of flowers. 
As soon as the leaves attain a height of one foot the ground 
should be mulched with manure to stimulate growth and 
keep the moisture in the soil during hot, dry weather. After 
the first frost the corms should be taken up, left out for a 
few days to dry, and then stored over winter in a cool, dry 
cellar, the leaves having been previously cut off. Dahlias 
and cannas require a rich, deep, moist soil and do best in 
cool situations. Both are particularly attractive for their 
flowers, and the canna for its fine foliage as well. The 
Plants should be set out after all danger of frost is over and 
should be given a thorough cultivation and plenty of water 
during the growing season. The first hard frost will kill 
their tops, which should then be cut off, and the roots taken 
up, cleaned, and stored in a cool, fairly moist cellar. Too 
dry and hot an atmosphere is injurious during the resting 
period. The roots should be placed stem end down to prevent 
the juices which are contained in the stems from running 
down into the tubers and rhizomes and causing them to rot. 
They are sometimes packed in sand or sawdust or hung up 
in bunches in the lan
