4. To the Treasurer of the Sliedrecht Branch
This document is a businesslike letter from January 1942, written at a time when the Sliedrecht branch of the Nederlandsche Vereeniging voor Luchtbescherming (Dutch Association for Air Protection) was fully engaged in its wartime activities. The sender addresses the treasurer and provides an overview of the membership fees and other revenues he has collected, along with the payments already made. He sets out in detail the remaining balance and the additional income received, such as contributions from the municipality and proceeds from the sale of light‑shielding kits.
He also reports the expenses he has made, including subscription costs, receipts, and compensation for various tasks. The calculation shows that the expenditures are slightly higher than the income, after which the sender notes that the small difference can be settled later. He adds several outstanding receipts that may still be collected and refers to an invoice from a supplier that needs to be paid, asking whether sufficient funds are available.
The letter ends with a formal salutation and signature.
