—--- @¢e@-—_ 
Accounts of studies of dietaries of families and a boarding 
house, by the Station, have been given in previous reports, as 
follows: 
1. A boarding house.* 5. A machinist’s family.t+ 
2. A chemist’s family.* 6. A mason’s family.+ 
3. <A jeweler’s family.+ 7. Acarpenter’s family.t+ 
4. A blacksmith’s family.+ 8. A carpenter’s family.+ 
Five dietaries have since been studied and are here reported. 
They are those of: 
g. The family of the Station Agriculturist in winter. 
10. A mason’s family (the same as No. 6). 
11. A carpenter’s family (the same as No. 8). 
12. A college students’ club. 
13. The family of the Station Agriculturist in summer. 
The general plan of the investigation included an account of 
the amounts and composition of all food materials of nutritive 
value in the house at the beginning, purchased during and 
remaining at the end of the experiment, and of all the kitchen 
and table wastes. The amounts of different food materials on 
hand at the beginning and received during the experiment were 
added; from this sum the amounts remaining at the end were 
subtracted. This gave the amount of each material actually 
used. From the amount thus obtained and the composition of 
each material, as shown by analysis, the amounts of the nutritive 
ingredients were estimated. From these were subtracted the 
amounts of nutrients in the waste, and thus the amounts of 
nutrients actually eaten were learned. 
Account was kept of the meals taken by the different members 
of the family, and by visitors. The number of meals for one 
man, to which the total number actual meals taken was equiva- 
lent, was estimated upon the basis of the potential energy, as has
