In an opening 45 minutes dominated by Town it took until seven minutes before the break to take the lead.
Trialist D’s long-range strike wound up in the back of the net following a goalkeeping error to separate the two sides at the halfway stage.
After the break Korrey Henry bagged his first goal as an official Glover with a cool finish, whilst Town finished the match with seven Academy prospects on the pitch in a display of youth in Dorset.
After four competitive outings against Swansea, Bristol City, Bristol Rovers and Plymouth Argyle, manager Darren Way took the opportunity to rest the majority of his first-team.
Only Gary Warren, Henry and Alex Fisher started in Dorset, with five trialists, goalkeeper coach Steve Phillips and the Academy duo of Declan Rose and Gabriel Rogers completing the starting eleven.
Forming the substitutes bench, six of the Under-18s completed the matchday squad.
Seeing plenty of the ball in the opening quarter-of-an-hour Town encamped themselves in the Magpies half, but couldn’t test home keeper Kingsley Latham despite long-range strikes from Trialist B and Rogers.
Getting his first taste of first-team action 16-year-old central defender Rose provided an accomplished display, whilst newest recruit Henry looked lively up front as the Green & Whites pressed for an opening goal.
Looking more and more likely, Fisher fired an acrobatic volley just over from 12 yards before Trialist C drove a strike into the arms of Latham after a strong run from teenager Henry.
Playing out almost like a training match with attack versus defence it took Way’s mixed eleven until 38 minutes to break the deadlock.
Trialist D speculatively unleashed a half-volley from 40 yards catching Latham by surprise, who could only deflect the ball into his own net.
Proving to be the difference at half-time the same eleven emerged after the break but came under their first spell of pressure.
The Magpies enjoyed their best territory of the match up until the hour-mark but couldn’t test the veteran Phillips between the sticks for Town and subsequently fell two behind.
Fisher spotted the run of strike partner Henry and the West Ham Academy graduate made no mistake with the finish when one-on-one.
Now trailing further the hosts squandered a glorious chance to reduce the deficit when Alex Stafie latched on to Tyrique Spencer-Clarke’s backpass, but having rounded Phillips the Magpies man could only drag a shot wide.
Giving yet more game time to the youth, Way’s side ended with seven Under-18s on the pitch with Rose, Kacper Kowalczyk, Daniel Ojo, Lewis Dix, Spencer-Clarke, Nestor Shako and Neville Nzembela all helping Town to continue their impressive run of results in pre-season.
