10 a.m.
I expect that machine must have been referring to the following spring . Then there are those new style of barometers , the long straight ones . I never can make head or tail of those . There is one side for 10 a.m. yesterday , and one side for 10 a.m. to-day ; but you ca n't always get there as early as ten , you know . It rises or falls for rain and fine , with much or less wind , and one end is `` Nly '' and the other `` Ely '' -LRB- what 's Ely got to do with it ? -RRB- , and if you tap it , it does n't tell you anything . And you 've got to correct it to sea-level , and reduce it to Fahrenheit , and even then I do n't know the answer .
