L15.319.J— GOLDFINCHES AND LINNETS.— 

 For a dozen or two hard boil an egg each morning 

 and rub through a sieve with an equal weight of plain 

 biscuit (I use Middlemass' Digestive). I also provide 

 grated boiled carrot, and crushed hemp, linseed, and 

 canary. Hardheads, thistle seed, and properly har- 

 vested plantain are useful additions. Give shell 

 gravel, which witn all foods must be fresh "daily, 

 water also, and use a large cage covered over for say 

 ten'days. — A. J. L. Jones, 6, Fitzroy-street, W. 



115,320.]— ACCUMULATORS— A 4-volt lamp 

 will require a two cell accumulator, and a 6-volt lamp 

 three cells, the cells being connected in series, and if 

 charged for eight hours at full strength (i.e., change 

 the bichromate solution every three hours) by a 

 battery having one cell more than the number of cells 

 in the accumulator would probably light lamp for six 

 hours if the accumulator i3 carefully made. Each 

 cell should be constructed as follows :— -Interior of 

 cell about 6in. by 4in, by liu. ; take twa plates of 

 clean lead ^in. thick having tags of lead left on upper 

 edge for connecting up, score them horizontally with 

 a knife so that when in the cell they are like files with 

 the teeth pointing upwards, make a stiff paste 

 of red Lead and diluted sulphuric acid (one 

 acid, ten water) spread this on the plates about 

 1-16 in. thick and wrap round with flannel, two plates 

 should then be fixed side by side in the cell with 

 rubber bands and small blocks of rubber or glass be- 

 tween to prevent touching one another. If desired 

 the cell may now be Sealed at the top leaving a gas 

 vent end opening to pour in solution (dilute sulphric 

 acid 1 to 10) which should just cover the top edge of 

 the plates, the cells may now be connected in series, 

 and "formed" by along charge of about twenty- 

 four hours, the direction of thecurrent beingreversed 

 every four hours. After this they are ready for the 

 ordinary charging and use as above described. If 

 all this is too much trouble (as no doubt it would be 

 unless experience is sought) all parts, cells, plates 

 and finished accumulators and re-charging can be 

 \had at most electrical shops at moderate prices.—
