196. Sherrard, E. C, and G. W. Blanco. The preparation and analysis of cattle food, 

 consisting of hydrolyzed sawdust. Jour. Indust. Eng. Chem. 13:61-65. 1921. — Sawdust is 

 hydrolyzed with 1.8 per cent sulphuric acid for 15 or 20 minutes under a steam pressure of 

 120 pounds. The resulting liquor is neutralized and evaporated under reduced pressure to 

 the consistency of a thick syrup. The syrup is mixed with the sawdust residue and dried. —

198. Sparhawk, W. N. Suggestions for rating risks in forest insurance. Jour. Forestry 

 18 : 701-709. 1920. — Fire insurance rates for forests should be determined along lines similar 

 to those followed in other kinds of insurance, an outline of which is given. The damage 

 by a forest fire depends on the area burned and the relation between values before and after 

 the fire. Area depends on the number of fires, and the number of the contributing causes. 

 The area burned per fire depends on climate and type as well as inflammability, as do also the 

 values at stake and destroyed. A classification of forest risks is suggested based on cli- 

 mate, on forest types, on age groups, on inflammability, and on occurrence. The loss costs 

 may then be determined by a method similar to that employed in the ordinary form of insur- 

 ance and it should take but a short time to determine these losses if all agencies cooperate 

 for a few years. — E. N. Munns. 



199. St ARTE, H. W. Anjan (Hardwickia binata) coppice. Indian Forester 46:641-647. 

 1920. — The best season for coppicing this species is between August and November, the worst 

 from May to July. The height of the stump influences the reproductive power, 12 to 18 inches 

 furnishing the strongest shoots and below 12 the weakest. — E. N. Munns. 



200. Starts, H. W. Further experiments in Salai (Boswelia serrata) tapping in the Shirpur 

 east range of N. Khandesh Division. Indian Forester 46 : 578-580. 1920. — Trees with green 

 bark yield more gum-oleo-resin than dry-barked trees; those with short boles yield less than 

 those with long boles; and hollow trees yield more "drip" than sound ones though the total 

 yield is less. Heaviest yields were secured in the dry season and the best in the fourth 

 month after tapping. — E. N. Munns.

 300-305. 1920. — A paper read at the Hobart Forestry Conference. The insolvency of forestry 

 in Australia, the responsibilities of the Australian Forest Services, timber imports, the colos- 

 sal post-war timber requirements, financial reform, proper selling methods, efficient forest 

 organization including adequate finances, the subsidizing of forestry and the need for an 

 effective timber tariff are treated, followed by a round-table discussion. — C. F. Korstian.
