METEOROLOGIC CLERK EXAMINATION (Special-Series No. 1). For explanation of the "relative weights," and of the method of determining the "general average," see clerk examination, p. 190. The time allowed for this examination is limited to seven consecutive hours. The first, second, third, and fourth subjects of this examination are substantially the same as the corresponding subjects of the clerk examination, except that the third subject does not contain the exercise in "writing from dictation."

(d) 6 T. 3 cwt. 7 lb. 5 oz. Question 3. Divide 52.28178 by 3.0017, and multiply the quotient by 4.09. Question 5. What is the length of a fence required to inclose a rectangular piece of ground 121 feet wide containing one acre? (4,840 sq. yds.=1 acre.) Give work in full. Question 6. A grocer sells goods to a customer for $352 by weights averaging 15} ounces to the pound. He afterwards sells said customer goods for $320 by weights averaging 16 ounces to the pound. How much does the grocer make or lose by the false weights? Give work in full. Question 7. A merchant buys 42 gallons of whisky at $2.50 per gallon, and keeps it for three years. He then finds that he has lost 7 gallons by leakage and evaporation. Estimating the value of money at 6 per cent, per annum, how much per gallon must he charge in order that he may realize the full amount of the cost, including the estimated interest. Give work in full. Question 8. The owner of £4,500 in English consols (3 per cents) sells them at 96, and invests the proceeds in 6 per cent. $100 bonds which he buys at 108. What is the difference in dollars and cents between his income from the consols and from the bonds? (£=$4.85.) Give work in full. Question 9. What is the weight (in tons, cwt., etc.) of the water which fills a cistern 9 feet 8 inches long, 9 feet 4 inches wide, and 6 feet 9 inches deep, a cnbie foot of water weighing 1,000 ounces? Give work in full. Question 10. A grocer pays 18 cents per pound for coffee and roasts it, losing 10% of the weight in the process. What must he charge per pound for the roasted coffee in order to make a profit of 20%? Give work in full. SIXTH SUBJECT-Meteorology. Question 1. What use is made of barometers by the signal service? Question 2. Define an isothermal line? Question 3. How does the sun heat the atmosphere? Question 4. What instrument is used to measure the velocity of the wind? Question 5. From what directions are the prevailing surface winds within the equs torial system? Question 6. Give Loomis's explanation of the formation of dew. Question 7. State the conditions that favor the formation of hoar frost. Question 8. State the accepted classification of clouds. Question 9. Define a storm. Question 10. In what respect do cyclones or hurricanes differ from tornadoes? SEVENTH SUBJECT-Use of meteorological tables. Question 1. Find the mean of the two following series of temperatures: Question 2. Convert the following Fahrenheit temperatures into centigrade to the nearest tenth): 86.0°, 77.2° 10.0°, -40.0°. Question 3. Convert the following inches into millimeters (to the nearest tenth19.760, 10.055, 17.994, 18.518. Question 4. Find from the tables the dew point and the relative humidity for the following pairs of readings of the dry and wet bulb thermometers: Question 5. Reduce the following barometer readings to freezing point: Question 6. For an observed barometer reading reduced to freezing point, equal to 27.42 at an altitude of 2,410 feet, what is the reading reduced to sea-level, the mean temperature of the air being 55.0? At an altitude of 5, 470 feet and the reading 23.75 reduced to freezing point, what would be the reading reduced to sea-level, the mean temperature being 14? Question 7. Given the formula p=.005 12. In which p-pressure per sq. ft., and V=velocity in miles per hour. Compute to the nearest tenth the velocities corresponding to these pressures: Question 8. Convert the following velocities, feet per second, into meters per second (to the nearest tenth): Question 9. In longitude 105 west at 8 a. m., what is the corresponding 75th meridian time? At 8 p. m. 75th meridian time, what is the corresponding local time in longitude 70 west? Question 10. The following means of barometer readings having been obtained, shorten to two places of decimals, having regard to the correct figure to be adopted when the rejected portion is exactly half of the last place of figures retained. TYPOGRAPHIC DRAFTSMAN'S EXAMINATION (Special-Series No. 2). For explanation of the "relative weights," and of the method of determining the "general average," see clerk examination, p. 190. The time allowed for this examination is limited to nine consecutive hours. The first subject is substantially the same as the fourth subject of the clerk examination, and the second subject is substantially the same as the geography of the sixth subject of the railway mail clerk examination, p. 251. The time occupied by the competitor in executing the work is taken into consideration in marking each subject. THIRD SUBJECT.-Computing. Question 1. The distance between two points on a map, having a scale of 6.55 miles to an inch, is 22.35 inches. Give the distance in miles. Give work in full. Question 2. The actual distance between two cities is one hundred miles. The distance between those cities on a certain map is four inches. What is the fractional scale of the map? Give work in full. Question 3. The two sides inclosing an angle of ninety degrees measure 117.25 and 93.5 feet, respectively. Give the area of the triangle. Give work in full. FOURTH SUBJECT.-Tracing. The applicant is given a portion of a topographic map, and is required to trace it on tracing-linen with India ink. FIFTH SUBJECT.-Drawing from field sketch. Transfer to drawing paper and ink the following chart: [NOTE.-This exercise is designed to test applicant's ability to transfer topographic drawings from original field sketch and to perfect the same in India ink. Especial care should be taken to produce sharp, uniform, and unbroken contour lines. Drainage should be lettered in italics (caps and lower case); mountain and other hypsographic names in block letters (caps); towns, trails, and wagon roads in upright Roman letters (caps and lower case), and railroads in inclined block (caps).] |
