Label Bar Chart from data

Given

mydata={{44970, 2357.7}, {54324, 1859.34}, {49500, 1797.44}, {54161,
  1432.26}, {49505, 1421.2}, {49605, 1292}, {54640, 1260}, {39503,
  760}, {49525, 711.31}, {43324, 617.1}}

This should be simple, but I can't seem to find the answer. I want a
BarChart of the second values {2357.7, 1859.34,....}, labeled with the
corresponding first value. This comes close, but all "bars' are
labeled with 44970, not sequentially.
;
BarChart[{#[[2]]} & /@ mydata, ChartLabels -> {#1} & /@ mydata]

The actual data is much larger, precluding simply entering the ten
values given above. Can someone point me in the right direction?

Thanks in advance
