becomes warm. To avoid the damage thrips do, four measures are effective. 
Plant early. Plant clean, treated bulbs. Keep them reasonably moist and well 
cultivated, with no weeds. ; 
The total elimination of thrips appears impossible. A few are bound to 
appear as the weather becomes warm. 
We therefore begin to dust with D.D.T. when plants are about 8” tall. Any 
hand duster will do. We use a powder containing 5% D.D.T., 45% Sulphur and 
50% inert ingredients. Dust in early morning when the plants are moist with 
dew. That will cause the powder to stick and remain effective for a week or 
two. Four to six dustings before flowering will control thrips tho in a field 
where various sizes have been planted and where flowering lasts for several 
weeks we consider it advisable to dust again once or more, the next morning 
after flowers are cut. We have not seen flowers or buds damaged by D.D.T. 
This powder can be had most anywhere under one of several trade names. 
Treating Bulbs. We have recommended various dips and treatments for 
bulbs but have rejected all when we later found that some injuries resulted to 
the bulbs. Now we dust our bulbs with the same D.D.T. powder. It keeps aphis 
and mealy bugs away and kills the thrips. 
Naphthalein flakes sprinkled in the bulb containers which are then covered 
and allowed to remain about three weeks, will usually kill all thrips. But too 
long an exposure results in a little damage to the bulbs. 
The Lysol treatment kills thrips and their eggs. It also is useful in con- 
trolling the various bacterial and fungus diseases that attack the bulbs. Mix 
4 teaspoonfuls Lysol to each gallon of water. Soak the bulbs in this not over 5 
hours. Do this just before planting and plant in moist soil. Unfavorable results 
have been reported from soaking too long or by planting in a dry soil and thus 
prolonging the action of the Lysol. Some growers do not recommend this 
treatment. 
The bulbs we sell you have been treated with D.D.T. Plant large bulbs 4” or 
5” deep; small 3”; bulblets 2”. Twice their diameter apart. One can plant two 
rows, staggered in a 4” wide furrow or closer in a single row. Rows about 20” 
apart. Alkaline soils produce poor Glads. Soil should be neutral to mildy acid. 
Leaf mould or peat added is useful. Domestic peat is often harmful because 
alkaline. Use no fresh manure, but well rotted manure is good. Top mulch of 
leaf mould or imported peat. is good. 
Keep Glads growing with plenty of water and best culture for about two 
months after flowering. It is best to dig bulbs in the south, and necessary in 
the north. 
Sizes and Prices. L means “large,” size 1 and 2, 14.”-114” (or more) in di- 
ameter. M. is “medium” and includes No. 3 and 4 sizes, 4” to 14,” diam. S. 
means ‘“‘small,” under %” diam. Large and medium bulbs give good long spikes. 
Small bulbs usually bloom in most varieties and when planted early, given good 
culture and plenty of water they usually make fairly long spikes. Early planted 
bulblets often flower. Large blubs bloom earlier and throw more and longer 
spikes. Prices are for one bulb as elsewhere in this catalog. A dozen, all of one 
sort, costs ten times the price of one unless otherwise stated. Six are sold at 
dozen rate. Don’t forget Sales Tax in California. 
Substitution. If you order early there is likely to be no substitution, but 
when out of a variety we send another as nearly like it as possible and of equal 
or greater value. If you do not approve this, request no substitution. 
We are offering many of the newer and better varieties that have been in- 
creased to a quantity where they can be sold at medium prices. A few of the 
older ones, still desirable, are retained. 
Please Note. The following descriptions are brief, to save space. The prices 
are low, to save you money. But every one ranks tops in its color class. 
April. Beautiful pastel tone of Apricot. Tall, vigorous, early. L. $1.50 ea. 
Big Top. Light pink with carmine feather. 6 ft. tall. The gorgeous, im- 
mense flowers and height give great distinction. L. 20c ea.
