of　such　strength　that　some　essential　part　does　not　at　the　critical　moment　break　down　or　carry　away。　　He　may　have　to　improve　his　motive　power；　and　here；　again；　we　do　not　doubt　his　cunning。　　Motor　engines；　self…contained　and　burning　liquid　fuel；　are　yet　in　their　infancy；　and　the　extraordinary　emulation　now　existing　in　their　production　puts　it　beyond　doubt　that　every　year　will　see　rapid　improvement　in　their　efficiency。

We　do　not　expect；　nor　do　we　desire；　that　the　world　may　see　the　fulfilment　of　the　poet's　dream；　〃Argosies　of　magic　sails〃　or　〃Airy　navies　grappling　in　the　central　blue。〃　　We　would　not　befog　our　vision　of　the　future　with　any　wild　imaginings；　seeking；　as　some　have　done；　to　see　in　the　electricity　or　other　hidden　power　of　heaven　the　means　for　its　subjugation　by　man；　but　it　is　far　from　unreasonable　to　hope　that　but　a　little　while　shall　pass；　and　we　shall　have　more　perfect　and　reliable　knowledge　of　the　tides　and　currents　in　the　vast　ocean　of　air；　and　when　that　day　may　have　come　then　it　may　be　claimed　that　the　grand　problem　of　aerial　navigation　will　be　already　solved。
