312 ANNUAL REPOETS OF DEPARTMENT OF AGRICULTURE. 



tallow, are a little less thoroughly digested than those with low 

 melting point, like lard and butter. Kafir corn, milo maize, feterita 

 meal and other products were found to compare favorably with 

 similar corn products in digestibility of their carbohydrates. Their 

 protein was not quite so thoroughly assimilated. Palatable dishes 

 can be made from these grains and their use will help to make the 

 diet varied. For this and similar reasons such grains are worthy of 

 more extended use in the region where they are grown and else- 

 where. Studies of honey showed many new and improved ways 

 of using it in the home in the preparation of palatable dishes. 

 Work was also carried on regarding the preparation of rice for 

 the table and its place in the diet, and household uses of citrus and 

 other fruits. 



As a result of studies of spots and stains and their removal from 

 clothing and household textiles, methods were found which will 

 greatly aid the housekeeper in the care of such materials. Simi- 

 lar studies regarding the cleaning and care of other household 

 equipment are in progress. The studies of household labor under- 

 taken with the respiration calorimeter proved in general that the 

 choice of equipment is an important matter, making it clear that 

 poor equipment means a loss of labor and furnishing data to show 

 how great the loss is. Of the types of labor so far studied (dish- 

 washing and sewing), the former makes decidedly greater demands 

 on the worker's strength than the latter. A noteworthy feature of 

 such experiments is that they yield quantitative data and so make it 

 possible to discuss such questions with a greater degree of accuracy 

 than has hitherto been possible. 



In addition to the above, which represent the more important 

 features of the work, the usual routine matters received attention. 



The publications issued included a Yearbook article on the selec- 

 tion of household equipment and two Farmers' Bulletins, one on 

 kitchen arrangement and equipment and the other on honey. 



As in previous years, the home economics investigations were in 

 charge of Dr. C. F. Langworthy.
