Suspense is Hostiler than Death — Suspense Account

The term Suspense Account is recorded in quotes of Oxford English Dictionary since 1869, but this poem was written around 1863. From Google books, we can find the term in 1806 (Reports from Committees of the House of Commons) already, so the term was known when Dickinson wrote it.

Suspense－is Hostiler than Death－¹
Death－tho'soever Broad,
Is Just Death, and cannot increase－
Suspense－does not conclude－

But perishes－to live anew－⁵
But just anew to die－
Annihilation－plated fresh
With Immortality－

(F.775/J.705)

I will just add, that it being desirable not to blend this transaction with the deposits made by the Receiver to the credit of the Bank of the United States, you will be pleased to raise a temporary suspense account in your books, ─ House Documents. Letter from the Treasury Department (1824)
