1851 Great Exhibition: Official Catalogue: Class VIII.: John Robertson
18. ROBERTSON, JOHN, Limehouse Hole, Poplar — Manufacturer.
Coils of cordage, manufactured from tarred Russian hemp, white Manilla hemp, and tarred New Zealand flax (Phormium tenax).
[The valuable and remarkable product, commercially known as New Zealand flax, is the fibre of a plant indigenous in that country and in Norfolk Island. The fibre is obtained from the leaves of this plant, and in many respects rivals that of hemp for toughness. The plant belongs to the natural family Liliacece: its cultivation in other than its native districts has hitherto been attended with indifferent results.—R. E.]
Patent gun trumpet, for fog or alarm signals. Models, showing patent slide tiller.
