Replenisher Gauges for 155mlll Guns. The Ordnance<br />
Department is investigating the practicability of providing<br />
replenisher gauges for 155mm guns (all types). These<br />
gauges will simplify the service of the piece in that no<br />
measurements will be necessary except that the gauge on<br />
the 155mm Guns M1917, M1918, and modifications, will<br />
have to be measured when oil is being drained. The elevation<br />
setter and the gun pointer will watch the gauges on<br />
the M1917 type and the 1\11type guns, respectively. These<br />
I<br />

gauges will eliminate the number five man from the gun<br />
crew of the M 1917 type gun during firing, and will relie\'e<br />
the gun commander of the M I type gun of the responsi<br />
bilit)' of measuring the replenisher after every tenth round<br />
Coast and Geodetic Survey Charts. Coast and Geodetic<br />
Survey charts on a scale of 1/80,000 have a wide variet)' of<br />
uses in harbor defenses. Such charts are required by battery,<br />
group and higher commanders to depict the field of<br />
fire, with limiting azimuths and ranges, and dead areas<br />
They are needed to show the grid used in identification an<br />
indication of targets. At present these charts may be 0<br />
tained by requisition on the service command but no deh<br />
nite basis of issue is prescribed. The Army Ground Forct'S<br />
is taking action to include the charts in Corps of Enginet'<br />

Replaceable Spindle Plugs for Seacoast <strong>Artillery</strong>. Co<br />
ments appearing in the reports of target practices indic~t<br />
that considerable trouble is being experienced in extracnn.,<br />
fired primers. While the basic cause is probably imp~o<br />
cleaning of the primer seat and vent, it is considered like<br />
that new obturator spindle plugs are required in anum<br />
of guns.<br />
The Chief of Ordnance has advised the Coast Artill<br />
Board that spindles with replaceable obturator spindle p~u<br />
are available at \Vatervliet Arsenal, and can be obtam<br />
