For swine: 3 grain (injected). 
For fowls: 50 m. grammes (given internally). 
For frogs: 2 m. grammes per kilo. (injected). 
In this case, as no frog weighs a kilo., a calculation is required. Say 
twenty frogs weigh 1 kilo., then ~ m. gramme is the dose to be injected to 
cause death. 
For mice and rats: 2°83 to 24m. grammes per kilo. (given internally). 
For snakes: 28:1 milligrammes per kilo. (injected). 
Yor a horse: 10 grains (given internally). 
For a human being: 4% grain, or 88m. grammes (injected subcutaneously), 
will kill an ordinary man weighing 150 lb. 
Taking the weight of a bandicoot at 2 lb., and the amount of strychnine 
on a grain of corn 31m. gramme (1 grain = 54m. grammes), then it will be 
seen that out of the 30 grains, or 1,620 m. grammes, far more than sufficient 
poison lies on each grain to kill any adventurous bandicoot which may conduct 
foraging operations on the newly sown field. 
TOBACCO SOILS. 
tx our article on tobacco-growing in the January number of the Journal, one 
statement as to a good tobacco soil is liable, as Mr. Nevill points out, to be 
misunderstood. He says that “‘ bright” tobaccos are grown in Virginia on the 
thin sandy soils. The “heavy’’ tobaccos, on the other hand, are grown on good 
soils, yet not on such as produce a rich, rank vegetable growth. Thus, our wheat 
lands would be utilised for heavy tobaccos, the more sandy soils for bright 
tobaccos, whilst the deep, rich, alluvial tropical scrub soils would not be so * 
suitable for the crop until their wonderful richness has been to some extent 
modified by repeated crops of, say, sugar-cane, maize, &c.

WHAT TO DO WITH THE EARLY MAIZE. 
Tyr serious losses in the early maize crop which have been entailed on farmers 
lately by the continued absence of rain might, to a large extent, be obviated if 
they would follow the advice so frequently given in this Jowrna/, and indeed in 
all other agricultural journals—to turn the whole crop into ensilage. Hundreds 
and thousands of acres of fine green maize, which would never produce sufficient 
cobs to make it worth harvesting, have been allowed to go to waste. By-and-by 
we shall see the miserable spectacle of vast masses of what is just now 
splendid cattle feed put in heaps, and burnt off to get rid of it. ‘Time and again 
liave the farmers been warned to provide against possible droughts, by building 
ensilage stacks, or by the erection of silo buildings, but mostly the advice is 
disregarded, and when the evil time comes their stock are starved, many die, 
and solid cash has to be expended for the purpose of buying feed both for 
dairy cattle, pigs, and farm horses. : 
The building of an ensilage stack requires no expert. Any good farm 
hand can doit. Of course a stack is not equal to a building, but the building 
costs money, whilst the stack merely costs labour—which is also money to be 
sure—but not in the same form or proportion. Supposing that a couple of
