A part of thiij map, showing only the most important features, is put 

 into this leaflet to serve as a guide. 



It will be seen that the University is made the central or starting 

 point. With a few hints it is believed that every school can make a 

 good beginning this year on a natural history survey of the region near 

 their schoolhouse, and in the preparation of a map to go with the survey. 



Preparation of the map, — It is well to have the map of good size. 

 A half sheet of bristol board will answer, but a whole sheet is better. 

 About the first thing to decide is the scale at which the map is to be 

 drawn. It is better to have the scale large. Twelve inches to the 

 mile would be convenient. Divide the map into squares, making the 

 lines quite heavy. If so large a scale were used it would be ad- 

 vantageous for locating places to have the large squares divided into 

 square inches, but much lighter lines should be used so that there will 

 be no confusion with the lines representing the miles. 



Locating objects ofi the map. — The corner of the schoolhouse con- 

 taining the cornerstone should be taken as the starting point. If there 

 is no cornerstone, select the most convenient corner. Put the school- 

 house on the map anywhere you wish, probably the center of the map 

 would be the best place. In the sample map the University is not in 

 the center as it was desired to show more of the country to the south 

 and west than to the north and east. 



The map should, of course, be made like other maps, so it will be 

 necessary to know the four cardinal points of the compass before 

 locating anything on it. Perhaps the schoolhouse has been placed 

 facing exactly north and south or east and west, that is, arranged with 

 the cardinal points of the compass ; if so it will be the best guide. 

 If you are not sure determine with a compass. With it the points can 

 be determined quite accurately. Having determined the points of 

 compass, commence to locate objects in the landscape on the map as 

 follows : Get their direction from the starting point at the corner of 

 the schoolhouse, then measure the distance accurately by rimning a 

 bicycle on which is a cyclometer, straight between the starting point 

 and the object. The cyclometer will record the distance accurately 

 and it can be read off easily. If no bicycle with a cyclometer is 

 available one can use a long measuring stick, a tape measure ot even 

 a measured string; but the bicycle and cyclometer are more con- 

 venient and accurate, especially when the distances are considerable.
