295.1862. Savior! I’ve no one else to tell –

Adam, In your explication above, you ask:

“Could “mound” be a slant allusion to pregnancy? Has the narrator, the dead living woman, somehow hindered a pregnancy, or had her pregnancy hindered?”

Emily Dickinson herself answered your question in the two variants of F295: Variant A is a prayer to Christ, and Variant B is a prayer to God the Father:

295A.1862. Savior! I’ve no one else to tell –

Savior! I’ve no one else to tell –
And so I trouble thee.
I am the one forgot thee so –
Dost thou remember me?
Nor, for myself, I came so far –
That were the little load –
I brought thee the imperial Heart
I had not strength to hold –
The Heart I carried in my own –
Till mine too heavy grew –
Yet – strangest – heavier since it went –
Is it too large for you?

I think F295A is ED’s confession that her pregnancy [mound] miscarried, and she’s asking Christ to accept her baby into Heaven, even if she is not accepted.

295B.1862. Father – I bring thee – not myself –

Father – I bring thee – not myself –
That were the little load
I bring thee the departed Heart
I had not strength to hold

The Heart I cherished in my own
Till mine – too heavy grew –
Yet – strangest – heavier – since it went –
Is it too large for you?

I think Variant B is also a prayer, this one to God the Father, to accept her dead baby into Heaven.
