To fix targets in the sawdust, attach to _Observation Practice Holders_ consisting of iron pins grooved at the top to hold targets. _Care must be taken to remove all sawdust and grit displaced by bullets from the falling target clips and other mechanism, or their action may be clogged. A brush should be used to clean the mechanism after observation practices._ 7. =Landscape Targets.=--The official handbook above referred to contains information as to fixing landscape targets to the framework of the Solano Target in position for instruction in firing (Fig. 57). VIII. SOLANO ELEMENTARY AND INSTRUCTIONAL TARGETS.[34] 1. In _Musketry Regulations_, para. 361, it is laid down that in carrying out training on miniature ranges _due regard must be paid to the visibility of service targets, and bull’s-eye targets must be used for the first few rounds only_. In para. 206 (iii) of _Musketry Regulations_ (see Sec. 17, para. 4 of this book) focussing the eye on the fore-sight of the rifle instead of on the object is indicated as a common fault which instructors must guard against in elementary stages of training. This error is common when bull’s-eye targets are used, and unless remedied will adversely affect shooting at service Targets, on which the eye must be focussed, and which must be watched closely when firing.
