 TRAINING. 



(See plate opposite page IS.) 



1. Soil-box with glass front, showing five strata of soil — clay loam, 

 brown sand, fine white sand, coarse gravel, blue clay — obtained in an 

 excavation near the School. A scale-label attached to the side of the 

 box gives the thickness of each stratum. 



2. Insectary. — The sides of glass, 12 x 32 inches, above wood 5 x 32 

 inches. Four inches of soil in the bottom. The cover a movable lid 

 framed on fine wire gauze. 



3. A box containing sixteen samples of soil. 



4. A box with slanting glass front, showing the development of 

 seedling roots against the glass. 



5. A mineral box containing 42 small boxes bedded on excelsior, each 

 containing a different labelled mineral and covered with glass, so that 

 the latter makes a lid for the specimen boxes. Each mineral is bedded 

 below, so that the specimen is held up agaiust the glass. 



6. An observation beehive with ventilation, suited to receiving one 

 Langstroth frame. In use, this is set against a locked window-sash, 

 with an opening for the admission and exit of the bees. The bees can- 

 not enter the room, although the hive is set inside on the window-sill. 

 Side-flaps of wood or cardboard, or a draping of cloth, may be used to 

 keep the hive in darkness when not under observation. 



7. An aquarium containing two mud-puppies, a crab, and some 

 water-weeds. The mud-puppies could not be kept still, hence their 

 forms are not defined in the photograph. 



8. A slat plant-press, 12 x 18 inches, with straps for pressure. 



9. An insect spreading-board. 



10. A box containing the stages of an insect from egg to imago. This 

 box rests upon exhibit No 3. The one beside which 10 is placed is a 

 weed-seed plaque similar to No 12. 



11. The prepared skin of a " hog-nose " snake, which a farmer taking 

 to be a venomous species, speared with a fork. It lived a few months 

 at the school, but finally succumbed to the injuries received at the time 

 of its capture. 



12. Weed-seed plaque for thirty kinds of seeds, made of plaster of 

 Paris, the receptacles being shallow holes bored with an inch auger. 

 The plaque is covered with the glass upon which the plaster was poured 

 to set. The seeds can be studied with a lens through the glass cover. 



13. Weed-seed holder, made by attaching rubber washers to a pane 

 of glass, covering them with another pane, and "passe partouting" 

 the panes together. 197
