Subject I.— The Haulage in Shafts and on Underground Planes; also the Strength of Haulage Ropes and Chains. 1. It is required to wind 300 tons per 8-hours shift up a shaft 600 ft. deep. With 901b. steam-pressure at boilers, and assuming coupled engines with drum on crank-shaft, give diameter of cylinders, length of stroke, and size of drum required. 2. Describe and sketch a good form of detaching-hook for the prevention of overwinding ; also catches for arresting a cage in the event of a rope breaking. 3. Sketch in detail a headgear (poppet-heads) combining strength and rigidity with the least amount of material. 4. What are the various forms of self-acting inclines? Give conditions under which each form can be most advantageously used. Show under which system the greatest amount of material may be transported, and what other advantages (if any) are possible. Also show how and under what conditions incline sets may always be sent down one side instead of on alternate sides. Subject J.— The Effect that Faults, Slides, and Mullock-bars have on Lodes, and how to ascertain the Direction of Slides and Heavals. 1. Describe fully what is meant by throws and heaves in lodes, and the effect they produce. 2. In working on a lode of quartz having a bearing of due north, and it was cut off by the dislocation running east by north, having an underlie to the south, in what direction would you drive to pick up the lode again, and give your reason fully for same ? 3. If you were driving along a lode that was cut off suddenly by mullock, how would you ascertain whether it was a slide or merely a bar of mullock ? 4. If a lode cut out in depth, what indicator would you follow with the view of getting the lode again at greater depth ? Subject X. — A Knowledge of Underground Surveying, and of making Plans of the Underground Workings, showing the Dip or Inclination and Strike of the Reefs or Lodes. 1. What is a compass ? In what does a prismatic compass differ from an ordinary compass, and what are its uses ? Explain what is meant by declination and dip. 2. What is the average difference in your district between a magnetic bearing of N. 23° 15' E. and the true bearing ? 3. Reduce the following traverse; give the distances on the meridian and perpendicular; compute the area enclosed when extremes are joined. Distances given in links. N. 6° 14' E , 486 links. N. 15° 48' E., 1,538 „ N. 48° 16' E., 1,296 „ N. 19° 35' E., 246 „ S. 11° 50' E., 963 „ 4. Describe to the Examiner the adjustments of any theodolite, and observe an angle. , 5. State the regulation marks and give the limits of the different kinds of claims. 6. State your experience as a surveyor or surveyor's cadet or assistant. Subject L.— A Knowledge of the Different Rocks where Gold, Silver, Tin, Copper, Zinc, Lead and Antimony are found, and the Formation of Lodes and Leads. 1. What metallic ores are usually associated with granite slate, propolyte, serpentine, and limestone respectively ? 2. What is the composition of the chief ores of silver, lead, tin, antimony, copper, and zinc, and where are they found in New Zealand ?

Questions used in the Examination of Battery-superintendents for Certificates. Subject A.— The Different Modes of reducing and pulverising Ores. 1. State where and by whom you were employed, and give the dates you were engaged in crush-ino--batteries where the bullion was recovered by cyanide-solution treatment. 2. In constructing a stamp-mill of forty stamps of I,loolb. each, give the dimensions of the stem, the head, shoe, and tappet, to correspond with the weight. Also show by calculation the maximum number of blows per minute that each stamp can give without falling on the cam, the height of drop being 7 in. 3. If you were constructing a forty-stamp mill with stamps of 1,0501b. each, the height of drop being 8 in. and number of drops 95 par minute, show by calculation the horse-power required to work the mill; also the quantity of water required to give the necessary horse - power by using a Pelton water-wheel under a head of 160 ft., the wheel giving 80 per cent, of the actual power of the water. Likewise show by calculation the diameter of the nozzle required to discharge the actual quantity of water on the wheel. 4. Describe how you would construct the foundations for a stamp-mill, give a sketch of same, and show how you would bed the mortar-box. 5. Describe fully the different classes of machinery employed in New Zealand for crushing quartz, the quantity of ore that each would crush in twenty-four hours, the cost of wear-and-tear per ton of quartz crushed. 6. Describe fully the advantages and disadvantages of dry crushing. Give the distance you would set the dies in the mortar-box below the bottom of the screens, and your reason for same.
