APPENDIX. 
Buckthorn. Rhamnus catharticus. 
The juice from the berries of the buckthorn, mixed with 
alum and gum arabic, makes the sap green used in water colors. 
These berries are a violent medicine, and have a very unpleasant 
taste. The bark produces a fine yellow dye. 
Calceolaria. 
There seems to be an infinite variety of calceolarias, and 
they are favorite florists’ flowers. They are all natives of 
Chili and Peru. The name comes from calceolus, a slipper, 
owing to the shape of the flowers. 
Canary-bird Flower. Tropasolum peregrinum. 
This graceful climber, known to the Spaniards as “pajaritos 
amarillos,” also comes from Peru. It blossoms profusely, 
and, twisted around slender columns, makes a charming 
effect. 
Carrot. Daucus carota. 
The ancient Greeks seem to have cultivated the carrot, anu 
it has appeared on the tables of all the civilized nations ever 
since their time. Parkinson, who was botanist to King 
James I., tells us that in his time ladies wore the delicate, 
feathery leaves of the carrot in their head-dresses, instead 
of plumes.
