by numerous natural enemies, amongst which one of tho ladybird beotl-es, Rhizobius ventralis. is most conspicuous. Thanks to the courtesy of the New South Wjlps Department of Agriculture, we expect to be soon receiving a supply of this insect for liberation in some of tho infested plantations of the south ; but it is a matter for conjecture whether -the experiment will be a success, owing to the climate of South Canterbury being rather rigorous for the proper development of this little ladybird." That was published two years ago. These interesting little beetles arrived, and evidently ha\e been doing well, for within ' the past few days hundreds have been liberated among fresJi fields, and a thou.sand or so are to be tiansported some distance, so that there shall bo an intor•\fning infected district, which will bo isolated and between two fires — ladybirds advancing in armies from opposite directions. This one instance shows of what great value properly-conducted departments may be to the country. I should have said that the bulletin contains two fine illustrations of the gum tree scaleone natural size, one very much magnified. Now for my other reason. 1 have by me several of these bulletins, but I am afraid that they are neither known nor appreciated where they are known, because so few actually get into the hands of those j interested. Wouldn't it be a good thing ito send them to every school , and even a better thing to arrange with the illustrated weeklies to use the blocks in the weekly issues? Again, Technical and District High Schools might, when possible, have specimens sent to them, and pupils might bo encouraged to experiment in their own ' districts upon posts and their natural ' enemies. Indeed, we might go further still. These bulletins might be issued as supplements to the school papers which are. 'to be published. As it will be compulsory — or, at least, I assume &o — to keep a set of school papers in each school, there j would then be a set of bulletins always ready for reference.
