In the main the "proprietary" machines bnilt by private firms have lacked the all-round qualities of those turned out by the Government factory, to the Royal Aircraft Factory specification. In some they have failed from a constructional standpoint; under the exacting conditions of service the alighting chassis have sometimes proved inadequate; in other cases the weather-proof qualities of the machines have been found deficient. These defects have more than able to or under contract cases proprietary 2 1 not only shown themselves amongst machines, but also some of the best known of the French makes have failed a very sorry figure when submitted to the rigorous test of service c0nditions in real warfare.

The execution of these sensational feats of arms by our naval airmen must not be taken to nean that they could not have been performed equally well by menbers of the Royal Flying Corps, but rather that the latter are fully occupied by their regular daily work of military reconnaissance, and are certainly uo more than nnmerically sufficient for the needs af our Army in the field.
