The Sultan and Clara Butt Darwin Tulip Bulbs. 



Fig. 1. — Three bulbs of the Sultan in clumps as dug. These were planted as 7-centimeter bulbs; 

 all have flowered and reached mature size. Fig. 2.— The same as Figure 1, with the bulbs cleaned. 

 Note the flower stems on each bulb planted; in each group are two bulbs which will flower next 

 year. Fig. 3.— Five clumps of Clara Butt as dug, with some of the old hulls pulled off. The 

 bulbs planted were 7 centimeters in size, set 21 to the row. Note the character and arrangement 

 of the reproduction. Fig. 4. — Same as Figure 3, with clumps cleaned and separated. No'te that 

 although these have reached mature size, none of them flowered this year. Each 7-eentimeter 

 bulb planted has become 12 to 13 centimeters in circumference and "produced another which 

 win reach flowering size in another year, although all may not flower. This variety has an 

 appealing flower and is a good reproducer, two characteristics which make for conmiercial quahty.
