Analyses of Dried Blood.

These are excellent manures, and should prove especially valuable for topdressing grain- and grass-crops. Several manures were on the market a few years ago under the name of " animal guanos;" these were prepared from the offal of the freezing-works, by working it up with bonedust or phosphatic guano, and sulphuric acid. As will be seen by the analyses, they belong to the class of nitro-phosphatic manures.

The use of lime has become rather frequent of late years, especially in Canterbury; and beneficial results have in many cases been recorded. Three samples were submitted for analysis, and the results obtained show that each sample has been well prepared, and that the amount of silica and insoluble matter is not excessive. The percentage of magnesia is low in each case. This substance is generally considered to be detrimental when present in the lime to any great extent. The sample from Timaru (No. 680) is the best, and in all respects an excellent sample of lime for either agricultural or building purposes.
