 The restocking of all the waters of France will 

 be accomplished then easily, since, on the one 

 hand the officers of the roads and bridges will 

 answer for the requirements of the service, and

 of the shed, the guard-house, the digging of the 

 ponds, the purchase of tools, and of twenty acres

 8,000 francs, will suffice to commence the work,
