126 MISSOURI BOTANICAL GARDEN BULLETIN 



the food value is practically constant in the different grades. 

 The grains are whitened by a coating of glucose and talc, prac- 

 tically all of which is removed if the rice is thoroughly washed 

 before cooking. Rice is very nutritious despite the fact that 

 part of the protein, fat, and mineral matter is removed in 

 milling. If polished rice were continually used as the prin- 

 cipal article of food, a disease known as "beriberi" would de- 

 velop due to the lack of certain vitamines, but when the diet 

 contains a variety of foods, no harm will result. 



Like cotton, rice has several by-products. In China and 

 Japan rice straw is used for making brooms, hats, matting. 

 paper, sandals, and other articles. In this country the straw 

 has been used for stock food, but this industry is usually not 

 developed in rice-growing sections. The hulls are used for 

 fuel, packing material, and sometimes as a fertilizer. Fresh 

 bran makes excellent cattle food. 



UNUSUAL LATE-FLOWERING PERIOD OF PLANTS 



The dry summer of 1921 followed by a rainy and mild 

 period in September and October caused an unusually late 

 blooming season for plants in this vicinity. Some plants 

 which ordinarily flower in March and April started in on 

 a second period of bloom, and, due to the long season, many 

 fall-blooming plants have been blooming vigorously for several 

 months. Following is a list of the plants growing out of 

 doors at the Garden which were recorded as blooming as late 

 as November 9 :
