Ether with a speed of at least 3x10^4 m/sec?

Why in this experiment was it safe to assume that at some time of the year the earth should be moving relative to the ether with a speed of at least 3x10^4 m/sec??

The earth's path around the sun is not a straight line. The change in velocity from one side of the orbit to its opposite side would account for it. I haven't calculated the value, but it looks like that will be the difference.

However one must assume that the Earth can not drag the ether along.

Well, for that experiment, anyway.
