The silage taken from tlie 5 ft. depth, where the maximum tem- 

 perature did not exceed 37-5° C, was of a much paler brown colour with 

 a strong, somewhat acid, flavour, similar to that described in Mr J. 

 Thistletou Smith's silos. 



Two feet from the bottom of the silo where doubtless the temperature 

 of fermentation was lower though records were not obtained, the colour 

 was still brown but the smell was much more pungent and very un- 

 pleasant, and similar to that described in General Adlercrons silo. The 

 smell was most tenacious and when handled tainted the hands so that 

 even washing with soap and water failed to remove the unpleasant smell 

 for several hours. This silage in contrast with the previous two types 

 was not relished by stock. 



In the light of later experience, it seems probable that the chief 

 factor contributing to this condition was the rainfall upon July 17th and 

 1 8th, causing a certain amount of decomposition of the green crop in 

 the field, and resulting in some rainwater being conveyed to the silo 

 with this part of the crop. 



In 1918 the silo was filled at the bottom with rye and tares and with 

 oats and tares at the top ; both crops were autumn sown. The rye and 

 tares stood well whereas the oat and tare crop was somewhat but not 

 badly laid. Cutting commenced on July 1st when the rye was rather 

 old, the grain being full-grown but soft and the glumes dry; the tare 

 seeds were denting the pods which were well developed; the oats were 

 forward in milk. The crop was cut 24 to -18 hours in advance of filling. 

 This continued from July "2nd to July 5th, when the silo was full. It 

 was left over the week-end to settle and refilled on July 8th with oats 

 and tares cut the same day. During the whole period of filling the 

 weather was beautifully sunny and no rain fell. 



The following table gives a record of temperatures taken at or about 

 5 p.m. each day at first at daily and later at longer intervals.
