illustrating a single day's work 011 a set of 

 samples taken from the surface four feet. 



It is not, of course, affirmed that the amounts 

 of the different ingredients found in the soils 

 examined are actually in solution in the soil 

 moisture as the sample conies from the field, 

 although in my judgment the observations in- 

 dicate that this is likely to be the case for 

 most of the ingredients at least, but observa- 

 tions sufficiently demonstrative have not yet 

 been made to warrant such a statement as 

 fact. The five sets of determinations in each 

 group are, in a way, made on duplicate field 

 samples; that is, they are taken at the same 

 time from the same field but from alternating 

 plots, one of which, as tlie table indicates, has 

 received no treatment, the others having re- 

 ceived the amounts of stable manure indicated, 

 or the amount of guano. These samples were 

 taken early in the spring, only a few days 

 after the application of the stable manure and 

 fertilizers. 



Observations similiar to these are being car- 

 ried through the growing season on eight 

 types of soil in four different states, the sam- 

 l)les being taken simultaneously in the four 



different localities. All of the different fields 

 are tinder the same crop conditions, so that 

 any differences in yield may be determined 

 for comparison with the amounts of soil mois- 

 ture and the amounts of readily water-soluble 

 salts which the soils upon which the crops are 

 growing are found to contain. F. H- Kixc.

from the ' discovery ' expedition". 

 Dr. II. R. Mill, in Symons's Meteorological 

 Magazine for May, publishes some preliminary 

 results of the meteorological observations 

 taken on the British Antarctic Expedition near 

 Mt. Erebus. The Discovery was in winter 

 (piarters in a sheltered position twenty-one 

 miles from Mt. Erebus, in lat. 77° 49' S., long. 

 160° E. Among the observations three facts 

 are of special interest by reason of their bear- 

 ing upon the theorj' of the general circulation 

 of the atmospliero, which is just now much 

 in debate. Lieut. Royds, in charge of the 

 meteorological observations, reports tliat
