The modern abattoir; construction, installation, and administration, A. 

 MoREAU {I/Abattoir Moderne; Construction, InstaUation, Administration. I^aris, 

 1906, pp. XVI+'tll, figs. 90). — In this volume particular attention is given to 

 an account of the construction, installation, and management of abattoirs in 

 France. It is maintained that too little attention has been given to the tech- 

 nique of construction in these abattoirs, a majority being modeled upon that at 

 the Villette market. By way of comparison the structural details of abattoirs 

 in other European countries are also considered. 



Attention is also given to arrangements for slaughtering various animals, 

 cold storage, accessory industries coiniected with abattoirs, sanitary manage- 

 ment of abattoirs, and veterinary insi)ection of in-emises and animals.

 cussed in considerable detail. The larger part of the volume is occupied with 

 an account of infectious diseases of farm animals and iji-actical methods by 

 which these diseases may be held in check or prevented from occurring.

Irrigation in northern Italy, II, E. Mead (U. S. Dcpt. Agr., Office E.rpt. 

 8tas. lint. 190, pp. S6, pis. -',, figs. 2).— This bulletin is the second part of the 

 report of the observations on irrigation in Italy .made by Doctor Mead in the 

 summer of 1903, and deals with the section watered by the Adda and Adige 

 rivers, taking up especially the legal and institutional phases of irrigation and 

 describing the operation of canals controlled by the Government and those con- 

 trolled by co()i)eratiye associations of water users. 



The history and present status of the irrigation laws of Italy are given, with 

 some comparisons with American conditions. The development of irrigation 

 laws from the early Boman law to the i)resent time is sketclied and a statement 

 of the jn-esent law, enacted in 1SS4, is given. The unification of Italy as a king- 

 dom made the National Government the successor to all the water rights wliich 

 had hitherto belonged to the separate provinces, and one of its first acts was 

 the declaration of the iwblic ownership of all unappropriated public waters. 

 This was followed by the enactment of a law providing for the determination 

 of what are public waters and the comi>iling of a list of all rights to these wa- 

 ters, and making provision for the acquiring of rights in the future by grant 

 only. 



Concessions are now granted either by a law of the Kingdom or by an ad- 

 ministrative decree, and are always made subject to existing rights. As a 

 rule they are limited to thirty years, but perpetual rights may be granted by a 

 law of the Kingdom. While the law makes the nation supreme in matters 

 relating to the granting of rights for irrigation, it entrusts the exercise of this
