and .31 to .37 inch in case of the paper envelope. Dry moss is about 

 the same as asbestos and paper, the frost penetrating through the as- 

 bestos 1.60 inch, and through dry moss, under the same circumstances, 

 1.62 inch. Through wet moss the frost penetrated only from .7 to .9 inch 

 under same circumstances, showing that the latter material is more 

 effective, bulk for bulk, than either dry moss, dry paper, or dry asbestos 

 felt. This agrees with the results of other experiments I have tried 

 with wet moss, yet I think the weight of the latter will forbid its em- 

 ployment in ordinary cases. The paper and asbestos are excluded by 

 their cost and also by their weight. The relative weights of the sev- 

 eral substances are about as follows: Asbestos felt, 82; paper, 50; wet 

 moss, 20; dry moss, 3. The comparative weights of the asbestos and 

 paper are given exactly. Those of wet and dry moss are correct rela- 

 tively to each other, but possibly a little too low relatively to the other 

 substances. But evidently none of the other substances can rival dry 

 moss for our i)urpose, when eflQciency and economy are both considered.] 



February 13. — The shipment of eggs, suspended since January 24, is 

 resumed to-day. 



February 22. — As in former years we measure our eggs for shipment 

 in old corn cans, each one holding about 2,500. On 13th instant Mr. 

 Muuson found that, filled as usual, a measure counted out 2, 720 eggs ; 

 twice since then he has counted a measure full and found in one case 

 2,710, and in another 2,725. The record of shipments before 13th is cor- 

 rected accordingly, and since that date the measures have been filled 

 not quite so full, with intention to have 2,500 in each as near as 

 possible. 



February 23. — To-day I examined the most forward eggs in the river 

 house (No. 2): The eyes have not yet begun to color. To try their hard- 

 iness for packing, I took a tray of them and rapped it smartly six or 

 eight times on the table, making the eggs rebound into the air. 



February 25. — There were picked from the above tray 94 white eggs 

 and all were unimjjregnated. So I should dare to pack these eggs now. 



March 1. — Shipment of eggs concluded to-day; 645,000 have been 

 sent away, and 215,000 remain to be hatched and planted in Grand 

 Lake. 



March 3. — I return to Bucksport, leaving Mr. Munson in charge. 



5. — ISTOTES FROM ME. MUNSON'S RECORD BOOK. 



February 28. — The earliest eggs received from the Penobscot station 

 commence to hatch to-day. [Two hundred and sixty-seven thousand 

 eggs of Penobscot salmon were hatched here at the charge of Mr. Frank 

 Todd, of Milltown, N. B., the same being furnished free by the State of 

 Maine, to be planted in the Saint Croix, the boundary river between 

 Mame and Il^ew Brunswick. For the hatching and expenses Mr. Todd 

 paid the establishment $91.26. The eggs were received in three lots, 

 January 30, February 12, and March 11.— C. G. A.]
