It's great to be able to show that runes were being carved in the Netherlands. This is one of the 23 currently known Frisian rune findings: the Westeremden (a location in the North-East of the Netherlands) yew stick, found in 1918 and dated 5th-8th century.
It can be seen in the Groninger Museum.
Made of Yew (Dutch: Taxus, or IJf) which is not a tree that generally could be found in this area. The inscription reads like a blessing or spell for luck/happiness. To me, this is Frisian galðr:

Elmar Seebold (in 1990) reads:
ophæmu givëda æmluþ:
iwi ok upduna (a)le
wimôv æh þusë
Tineke Looijenga (in 1997) reads:
op hæmu jibada æmluþ :
iwi ok up duna (a)le
wimœd æh þusa
(Source)
Interpreted as something like:
luck (amluþ) stays (gibada) at home (op hæmu);
and (ok) at the yew (iwi) may it grow (ale) on the hill (up duna);
Wimœd has (æh) this (þusa)
Modern Frisians translate it into:
op de boerderij (heem) blijft voorspoed;
laat het groeien bij de ijf (taxus) op de terp;
dit is (eigendom) van Wimoed

Interestingly, this 5th-8th century Frisian Futhorc differs slightly from the more commonly known elder Futhark. (Context: the Elder Futhark in the Scandinavian areas transitioned towards the Younger Futhark in the 7th-8th century).
Here are a few interpretations by different writers:
