" While tlu! results of this test may not be convincing, the 1.5U0 birds eni- 

 jiloycd and the large number of eggs incubated, with the satisfactory average 

 yields of a chick from 2 eggs, does furnish data sufHcient to ivmove scruples 

 regarding the fitness of long-mated birds for breeders." 



Poultry investigatior.s at the Maine Agricultural Experiment Station, 

 C. D. Woods and G. M. (Jowell (?'. X. nc/it. Af/r., Bur. Aiiiiii. Indus. Jiiil. 90, 

 PI). Ji2, pU. J, fi()s. 2). — This is a revision of a bulletin of the Maine Station 

 (E. S. R., 1"), p. 1104). The new material which has been iiicoritorated consists 

 very largely of descri])tions of the station jxiultry plant, the methods followed 

 in poultry ex[)eriments, and the way in which data are recorded.

Preserving eggs, R. W. Tpiatcher (Wdsltiin/taii .s7(/. Bill. 11. pp. I)'). — The 

 relative value for preserving eggs of 1(» ]tcr cent and ."> per cent solutions of 

 water glass, of a mixture of limewater and salt brine (the limewater lieing 

 made by mixing a pound of quicklime and 0.5 lb. of table salt with 4 qts. of boil- 

 ing water), and of a commei'cial egg ])reservative were studied. The eggs 

 were placed in stone jars, 50 to a jar, and the li(|nids poured over them until 

 they were entin^ly submerged. The eggs were examined at intervals for 8 

 months. 



"These experiments show that eggs can be kept in good condition for home 

 use at least eight mouths by immersing them either in a water-glass solution or 

 in limewater and salt brine. Those preserved in water glass this year appeared 

 to come out in better ccmdition than those kept in the lime and salt mixture. 

 Other experimenters have succeeded in keeping eggs to their entire satisfaction 

 in solutions of water glass as dilute as 5 per cent, but the author's experience 

 this year was that a sti'ongei* solution gave a better preservation. It seems 

 jirobable that a solution halfway between the two which were used . . . would 

 be better than either of these, since it would doubtless give a better ])roduct 

 than the weaker solution and would not deposit sediment, thereby gradually 

 losing strength, as the stronger solution did." 



The author calculates that a i)ound of water glass properly diluted is sutli- 

 cient to cover 12 to 15 doz. eggs and that the cost of the preservative would 

 be less than one cent per dozen. 



" Each day's gathering of eggs may be )>acked immediately after gathering by 

 placing them in the jar and pcmring over them just enough of the solution to 

 cover them. This is better than to hold the eggs for several days, at the risk 

 of their becoming stale, in order to have n sullicient mnuber to fill the entire 

 ve.ssel at one time. 



"Eggs packed by . . . [the water glass] method will keep for some time 

 after they ar(> removed from the i)reservative solution. The author has used 

 some which have been out of the solution for four weeks without being able 

 to detect any deterioration in (niality."
