In the early ages man contented himself with the use of such tools and appliances as would assist him in the enlightenment of his labours. With the advancement of science, numerous motives, with modifications and adaptations, have been introduced to enlighten labours, and in many cases have taken the place of man, but it can hardly be said that this applies to shovels, although one of the oldest implements of labour; certainly, with the introduction of the steam shovel the labours of man have been considerably reduced, but the hand shovel of today is used similarly to that of years ago.If the principle of the hand shovel has not been improved upon, it must not be suggested that the manufacturers of this article are not endeavouring to improve its quality, and the main point with which the manufacturers have to contend is the production of an article which will give a maximum of durability combined with a minimum of lightness. In order to accomplish this they must select suitable material, and subject it to such heat treatment process that will produce a shovel having a maximum of hardness and toughness without being unduly brittle, and which will withstand the excessive wear to which it is subjected.In this article an endeavour will be made to explain (a) the manufacture of shovels; (b) the defects commonly met with-the cause of same and measures which are necessary to remedy them.Before doing so a brief description will be given of the class of steel used for shovels; this is an important factor, and a steel which is admirably suitable is a plain carbon one containing approximately 55 - 70% C., and closely resembles that used for the manufacture of railway rails. This plain carbon steel is very extensively used, although at present alloy steels are being utilised to a certain extent for shovel manufacture, and with suitable heat-treatment.
