Construction of large on-site detention pond to manage the stormwater runoff in the project area is not only expensive, but also a waste of developable land. To minimize the pond size, a systematic design of storm fl ow routing followed by model verifi cation is necessary. This study presents a challenging stormwater management design for a site located in a complex urban setting at Tallahassee, Florida, USA. The site, a 4.6-hectare (11.4 acre) wooded area, was developed into a swimming pool complex resulting in increased post-development runoff. This increased runoff was managed by designing an on-site pond, minimized by placing it in series with an existing downstream off-site pond of a closed basin. The available storage of the downstream pond was effi ciently used to reduce the upstream pond size. To minimize the on-site pond, the design considered rearrangement and re-sizing of pre-development basins that allowed releasing some portion of post-development runoff below its pre-development level in the directions where it was allowed to drain. The excess runoff generated from the area was routed through the on-site pond and discharged into the existing off-site pond, where all runoff was retained to meet the guidelines of a closed basin. The short duration simulation results (8-hr and 24-hr design storms) confi rmed signifi cant off-site runoff reduction for the postdevelopment condition. Besides short duration simulations, the extended simulation results (for the entire 1-yr period) also revealed that the on-site and off-site ponds can jointly manage all extreme runoff including the runoff of a historical extreme wet year.

as possible, to establish if possible a system of forestry which will produce lumber timber in less than 150 years, and mine timber in less than 100 years. The principal subjects discussed in the several divisions of the report embrace the topography, the limits, the agricultural lands, the mining and the forests of the reserves. Other topics include the water supply, parks species of timber, classification of timber, amount of available timber, and means of transportation of lumber. The report is furnished with an excellent set of illustrations and maps. It is a valuable contribution, well calculated to accomplish the purposes for which it was written, i. e., to furnish as full data as possible concerning our forests, and to waken a desire for their preservation.

241set. Jesus here has just been talking about doing something for others-and not just talking but acting it out. And his disciples are watching and wondering. Yes, they think, this is the way of life for me ; giving and not getting, serving rather than being served is the Christian way ; now we know. And Jesus said : If you know these things, happy are you if you do them '. Happiness is doing what you believe.Have you ever thought how much of our unhappiness is simply the result of not acting up to what we know ? On the crudest level, if I know that oysters disagree with me and yet can't resist swallowing a plateful some interior unhappiness is bound to result. But worse than a pain in the stomach is the pain in the conscience that comes with refusing to do what we know to be right. How many thousands are seeking psychiatric help across the country because they are suffering from a constant depression which may very well be caused by a refusal to act up to what they know to be right ? Conversely, aren't the happiest moments we know those in which we are conscious of having really responded to the way of life we know to be best ? We are expert in finding excuses for not following through on our beliefs, but the happiest people-and the happiest churches-are those who are really trying to close the gap between the things we believe and the things we do. ' If ye know these things, happy are ye if ye do them.' Well what things do we know ?i . First, we know-don't we-what the disciples knew as they watched the Master wash their feet: that Christianity means serving others in their need. A Christian is committed to a way of life in which selfishness gives place to compassion, and all our time, our talents, and our treasure are held in trust from God to be used as he directs. A church is not a religious club to which we pay our subscriptions in order to receive certain benefits, but a community that exists to offer the Gospel with all its healing power for body, mind and spirit, to everyone we are able to reach. We know this, don't we ? We know this is the Christian way.We believe in a Lord who gave himself-his body and blood-for others, and who calls on us to be givers too. ' If ye know these things, happy are ye if ye do them.' Happiness is doing what we believe.2. Then we know-don't we ?-that the worship and ministry of the Church must have a priority among the many interests, duties and enthusiasms of our daily life. We believe that Jesus is our Lord and Master, and that nothing matters more than being his active disciple. Here at the Table we confess that he is the centre of our life, that, as the Heidelburg Catechism puts it, ' I belong-body and soul, in life and in death-not to myself but to my faithful Saviour Jesus Christ '. So the support of his Church is not just one obligation among many, but an integral part of that loyalty we have for him. As we watch so many heart-breaking things happening around us to-day-the corruption, the crime, the cruelties and injustice, the apparent hardening of hearts and cynic...
