vestigators and students of 191, as compared with 160 in 1912, 

 147 in 1911 and 126 in 1910. The number of subscribing in- 

 stitutions was 30 in 1913, as compared with 29 in 1912, 25 in 1911, 

 24 in 1910, 20 in 1909, 18 in 1908 and 16 in 1907. The list is 

 given on p. 339. Of these Barnard College, the Crocker Re- 

 search Fund of Columbia University, Harvard University, 

 Kansas State Agricultural College and Radcliffe College are 

 new subscriptions. The receipts from the subscribing insti- 

 tutions and students' fees were $6,160 in 1913, as compared with 

 $5,175 in 1912, $4,574.99 in 1911, $4,150 in 1910 and $3,700.35 

 in 1909. The receipts from the supply department were 

 $14,554.40 in 1913, as compared with $13,966.35 in 1912, 

 $10,303.61 in 1911, $9,300.58 in 1910, and $8,549.55 in 1909. 



At the beginning of 1913 a new system of book-keeping was 

 established with the aid of Dr. Drew. While this may cause 

 some difficulty in comparison of the treasurer's report for the 

 current year with the preceding reports, it gives a much more 

 accurate idea of the real classification of expenses and the cost 

 of departments, and it is hoped that it may furnish the basis for 

 more complete comparisons in the future. The book-keeping 

 is now done at Wood's Hole, under the supervision of the treas- 

 urer, instead of in Boston as formerly; this is a great aid in ad- 

 ministration, as it enables the executive officers to keep closer 

 account of receipts and expenditures. 



Great improvements were made in the mess in preparation for 

 the past summer session. The dining-room was enlarged by 

 about 50 per cent., a wide covered verandah was built around three 

 sides of it; the kitchen w T as much enlarged and its ventilation 

 improved and a new laundry built. The expense of these improve- 

 ments, $5,720.16, was provided for partly by the earnings of 

 the mess $1,581.70, partly by subscriptions amounting to 

 $2,147.33 from a considerable number of subscribers, and partly 

 by current funds of the Laboratory to which the mess now stands 

 indebted in the sum of $1,991.13. 



The large increase of investigators was accommodated by 

 utilizing the Kidder Annex, the Yacht Club building, and every 

 available corner of the old buildings. The progress of the new 

 building was therefore particularly inspiriting in its promise of
