Among the equipment that the Martians have brought to earth, the Enbankment and Smelting Machines are often overlooked though they do represent feats of martian engineering well beyond that of Victorian London. The Enbankment Machine is a four meter long eleven legged mechanism that is notable for being entirely automated used for construction and mining purposes, consuming soil, gravel and other loose material through it's mouth and expelling it out a rear chute at the end of it's arthopodian body. This was either sprayed out to build enbankments, level terrain and other such activities or it could be put into a removable boxy hopper. The most notable feature of these devices is their autonomy. They lack anywhere where a Martian could sit and operate these vehicles and possessed an optical dome believed by scientists to be an electronic eye. By all indications, the Martians simply gave Enbankment Machines broad instruction which they executed with a minimum of input from their masters afterwards. This was witnessed by several observers and was remarked in the aftermath of the First Martian invasion where Enbankment machines had executed instructions given to them at Primrose Hill even after the martians that had given them said instructions had succumbed to disease. At the completion of that task they simply lined up and in a corner of a designated site and went dormant.





The reason why hoppers were used by Embankment Machines was to gather up clay to be used as Raw Materials in their Smelting Machines. These tall cylindrical devices could take said material and rapidly process it into cylindrical aluminum ingots. Operating continuously this machine could produce three ingots a minute, or over 17 tonnes of high grade aluminum a day. These ingots would in turn be fed into other fabrication machines used by the martians to produce additional equipment and vehicles. Forty two Smelting Machines were recovered after the war and played a major role in rebuilding the English Economy in the aftermath of that devastating conflict.
