APPENDIX 



The teacher is advised to procure, both for his own 

 information and in order to read passages to the scholars : 

 Gilbert White, Natural History of Selborne. 

 Charles Darwin, Earthworms and Vegetable Mould 



(Murray). 

 A. D. Hall, The Soil (Murray). 



E. J. Russell, JSoil conditions and ]plant growth (Long- 

 mans). 



Mr Hugh Richardson has supplied me with the following 

 list of questions, tnrough many of which his scholars at 

 Bootham School, York, have worked. They are inserted 

 here to afford hints to other teachers and to show how the 

 lessons may be varied. They should also prove useful for 

 revising and testing the scholars' knowledge. 



1. Collect samples of the different soils in your neighbourhood 

 — garden soil, soil from a ploughed field, from a mole-hill in a 

 pasture field, leaf mould from a wood, etc. Collect also samples of 

 the sub-soils, sand, gravel, clay, peat. 



2. Supplement your collection by purchasing from a gardener's 

 shop some mixed potting soil and also the separate ingredients 

 used to form such a mixture — silver sand, leaf mould, peat. 



3. How many different sorts of peat can you get samples of? 

 Peat mould, peat moss litter, sphagnum moss, turf for burning, dry 

 moor peat ? 



4. Find for what different purposes sand is in use, such as 

 mortar making, iron founding, scouring, bird cages, and obtain 

 samples of each kind.
